IIRC, Dago Red was asking for brass comparison of 50's.
This may substitute.

This is cut and pasted from
www.ammoguide.com
Join and do your own comparisons of bunches of carts they have listed there.
Overall, well worth the small subscription fee.

Most of the data is good,
but some of it is systematically bad data.

The gross water capacities are fictitious.
The 500 Jeffery drawing they have shows it to have a 30 degree shoulder. Just watch out for bogus data there.

For example, the water capacities of real 500 Jeffery and 500 Mbogo (aka 50-08) are both about 155 grains.

Ballistic Comparison:
Generated from actual load data submitted by members.
The velocities, energies and bullet weights seem to be averages of loads submitted there.

The 500 A-Square has been data-pointed with hot loads, realistic, except in the case capacity,
which is actually closer to 149.5, rather than the 133.5 that Ammoguide shows.

Very nice, thank you

Even more mystery surrounds the 577,600 class ctg
but this big 50 lineup is informative. Look at that 500 ahr, excellent.

thanks Ron -- great work ..

LOL -- so since the 500 AR has the most "data points" and the highest average bullet weight... and i shared loads from popgun to cannon, it drives the average down .. but the AR and the BM have a complete data set

It may be more realistic to show the top 3 loads and bullets .. in some cases, that would result in 9 loads, which the majority don't have posted!

for the record on the 500 AR
535 - 2400 is EASY
570 gr (hornady and a2) 2250 is easy, 2318 still aint maxed
600 gr same story 2250 is easy, 2318 may be a top load, but it aint maxed

Very Good RIP

I am not complaining about including the 50 B&M Long, so thanks! But it really is not in the same class as the big boys! First of course it is not .510 caliber as are the rest. Second is that concerning the 50 B&M it is not about the cartridge itself, but the platform-cartridge-bullet combination. The 50 B&M is on a tiny platform, (rifle), Win M70 WSM action and 18 inch barrel.

Maybe a closer comparison would be the 500 MDM, Win M70 long action with 21 inch barrel. Even though it is .500 caliber, it would be between 500 Nitro and the Gibbs. But it is also a lot about platform. Even with a heavy myrtle stock it comes in at 8.5 lbs.

Anyway, great effort and thanks!

Michael

Thanks Dr. Berry. Anyone ever made a 510 Improved Gibbs? Not that I would want one.

How about the 498 A-Square? It's a straight wall cartridge with a re-enforcing belt-my kind of cartridge! It would make a great ele cartridge for a double rifle.

Forrest,
Phil Shoemaker did one accidentally when his gunsmith got hold of a .510-caliber barrel, thinking it was .505,
and chambered it with a .505 Gibbs reamer.
Apparently it shot well after Phil realizided he needed to be loading .510-caliber bullets.

I don't have any first hand experience with it other than making some dummies using .505 Gibbs brass and .510 bullets.
Tried it with full length neck and 3.150" brass,
also tried it with shorter neck, about caliber length, and 3.000" brass length.

Ammoguide has a couple of .510/.505 Gibbs cartridges listed.

The catalogs of reamer makers show many variations of the .510/.505 Gibbs, going way back ...

At www.ammoguide.com there is a full length one,
and a ".510 Snipe-Tac."
The latter is the .408 Chey-Tac necked up.
Proprietor of that one claims 2350 fps with 750-grain bullets.

The Ammoguide comparison tool allows only 8 cartridges to be displayed at one time.
I'll see if I can pick an assortment of eight more "Fifties" to compare, from masterlist there.

Really? a 65K psi belted cartrdige is a GOOD idea in a doubel rifle? and it out performs tha 500 NE HOW

IF that's the case,load it down! It should also give good velocity needed for penetration with recoil levels that are tolerable for the average shooter.

RIP- Good data as always. The 500a2 certainly shines in your comparison. Its always been a favorite of mine for many reasons. I'm hurt though that you didnt include the .50-.600Ok. The illegitimate result of a pairing of the .600Ok and a .50BMG.-Rob

Ouch!
Jeffe,
You quoted shootaway so I saw it! Painful to my eyes!
No need to correct his typo on the ".495 A-Square" ... and I am sure he does not understand the desirability of a rimmed cartridge for a double, nor how much better the standard 500 NE 3" is than the hi-pressure belted, 2.800"-long .495A2 is for a double, yadayadayada ...
Your typing fingers will be dead and cold before he gets it.

Rob,
I don't recall seeing your 50/600OK listed,
I'll go back and look again.

Anyone with a pet wildcat or obscure production cartridge can join
www.ammoguide.com
for about $15/year,
or whatever it is now, it's a tiny sum.
Then post a few dimensions and it will draw your cartridge.
Then you get to enter your pet loads.

Thanks, RIP!
I love setups like that!

Rip
sorry about that.. the only think our VI seems to do well is go back and revised/edit/delete its posts...

But, I am happy to report, loads form the B&M and the AR constitute the bulk of all .500 loads..

One thing everyone needs to be aware of when comparing the data is the case capacities from AmmoGuide and Load from a Disk are just estimates from drawings, in some cases...I have weighed two with water to top of case...50-140 Sharps Jamison brass at 148gr H20 and a 505 Gibbs Jamison brass at 175 gr H20...both AG and LD posted different weights and I have found discrepancies in case measurements in several cartridges.

Not really a problem real world, but raises questions about the rest of the calculated data you get from the software.

The load data probably is accurate tho'.

I worked up a 510 Gibbs "Improved" in the LD custom design part...the Gibbs is already pretty much "improved" as is but by reducing the taper to a minimum it brought the total H2O capacity up to 180 gr...definitely a mind blower at either end.

Luck on your projects.

The guy who owns AmmoGuide lives out here, do you want me to ask him about anything?

I love AmmoGuide and have been over there for 3 yrs or so I think, have my rounds listed there like Jeffe and RIP. But I will say some of the loads for various cartridges are put there from the book, whichever book they might list and are not yet real loads from real rifles.

The loads that RIP, Jeffe, myself put on for our cartridges are real loads from real rifles--not from a book or computer generated. And of course we are not the only 3 that have loads there by any stretch, just saying watch where the loads are coming from is all.

Michael

other than Micheal's little runt, mine is the shortest!!

By the way you know, RIP and I are "FAMOUS"! We are in a book--Well our cartridges are in a book, RIP and I are not really mentioned, in the book, but none the less, I think, well, maybe we famous anyway!

I also don't know why, but RIP is pissed at me too about something?

Michael

There are only six more "50s" listed at
www.ammoguide.com
that I consider worthy of lining up against the .505 Gibbs and 500 Mbogo/50-08, for comparison:



Michael,
Yep, we're famous.

FOOBAR,
180 grains of water is indeed much closer to the standard .505 Gibbs gross capacity.
I'll have to look up what I got from measuring Jamison brass ...

fjold,
No need to bother him, I am sure he is doing what is best.
I just hope he doesn't can me for copying and posting these here.

Yes, Jeff, Michael, and Ed have been very busy at
www.ammoguide.com

I could add a lot more actual load data there,
for the 500 Mbogo (50-08) and the .395 Tatanka (40-07).

I could also add some more of my wildcat cartridges to increase the master list to more than only 743 cartridges:

.458/.338 Lapua Mag
.423/.338 Lapua Mag (Longer than Dakota's .423 Lapua Short)
.395/.338 Lapua Mag aka .398 Lapua Mag: Original!!!
.375/.338 Lapua Mag: Germans did it before me as the "9.5x69mm Tornado."
.395 Ruger Max
400/.395 NE 3" Aboriginal aka 10.03x75R

And then I could add many wildcats, and proprietary carts of others not listed there yet ... and load data ...

And then I could add load data for many wildcats that are there already ...

And then everybody here can join and add all of theirs ...

Rob, you too?

Pretty soon we will have the master list over 1000 carts.
Over 2000?

Michael... What was the capacity of your 500 MDM?
Funny thing I was looking at that supershort you sent and was thinking if you trim it to 1.4" you have a kind of 50 AE long or 500 JRH that would fit nice in a BFR already chambered for 50 AE or in an 1894 Marlin conversion. would be a fine pig gun. Mcphereson does the 50AE in an 1894 but loads it long. The 500 JRH is no slouch.

Yes, what was it actually?
Compared to the 114.7 grains H20 gross generated by www.ammoguide.com
for the "500 MDM Ultra" ... ???.?

Boomy and RIP

The actual H2O capacity is 129 grs. for the 500 MDM.

Well I ain't the RUNT anymore that 50 Fat Mac is shorter than the 500 MDM! I assume Jeffe was talking about "HEIGHT"? Fat Mac is a little fatter however. Looks Like in capacity I might still be the runt of the litter!

RIP you need to get your other Wildcats over there really!

Boomy

1894 Conversion? Are you saying that my super short, or derivative would fit in a 1894? I am not so sure it would (nothing new about that however) but if the 50 Super Short would come close to fitting, why wouldn't a 500 S&W fit? If it would, why ain't nobody done it yet???? OR have they? Sometimes I live in my own little world here!

You know I don't watch the news! You know, TV like CNN and things like that! Have not watched that sort of thing in more than 10 years or more! All of it BS so what's the point?

Something else, I hardly leave the compound unless I going on a trip! Noticed the other day I had not been outside the gate in 10 days! What's the point, everything I do, I do it here, there is nothing I need out there?

So you see, I might have missed something about a lever gun in 500 something! Wait, I have lever guns in .500s, just not 94s!

So ?????

Michael

MM .. anyone that falls back to "but did YOU shoot an elephant" is both arogant and shortsighted .. you see, the guy took a dump the same way a month before as a month after he shot a small shed.

Me? this is the big bore forum, not african hunting .. and if they want to trump up a popgun at 20% overloaded pressure, then, well, as long as I am not standing next to them, its their problem that they can't handle a little recoil and reality.

Its funny that the 500 AR gets "Shorted" due to the fact that I shared all my load dev, and not my "imagined" top loads.. like a 475 AM does.

anyway. here's to a good port and keeping primers from piercing!
jeffe

If you read this it will explain the short 50 thing. I was thinking 1.4" so to fit in a rechambered 50 AE from Magnum research too.
Mcphereson does a 50 AE conversion but just loads it out long.
2nd from the left
Now that would be the shortest

I swear I don't go "UP" there much at all anymore. Hardly ever post UP there. Can You Say "Pompous Ass"--It's the same as if you go to the "Safari Club Shows" POMPOUS ASS is the go word!

I feel at home here on Big Bores. Real shooters here, about guns, bullets, cartridges, what is real and not cooked up! Shooters, not someone who shoots a 100 rds in a 5 yr period, we shoot 100 rds of big bore in a day. (OK Today I only shot 37 rds of 416--18 rds of 458--6 rds of 500 MDM--6 rds of 50 B&M--and 24 rds of 9.3--Wait, 9.3 don't count-so that's only 66 rds says my calculator) but you know what I mean! I am quite sure there are so called great white hunters that don't shoot 66 rds in a year! Ahhh, don't get me started! Thank You!

As for the popgun--If I could only choose one (god forbid) it would be the lott for sure! I used my Win for thin (Pun Intended) and the Lott for heavy when I was shooting those antiquated cartridges before stepping up to the plate with my "RUNT GUNS"!

Has to be real-if not what is the point! Anyway, real is way the hell more than enough to do any job asked of it!!!!!!! Give me real everyday!

And one must also remember, "Velocity is not always your Friend" Temper the velocity to fit the BULLET being used!

OK Boomy

I will check out Mcphereson and the 94s!

Michael

Hey I got a DPMS in 300SAUM today, and another one on the way! It is going to be a perfect fit for a 2 inch 50 B&M and then later a 2 inch 458 B&M!

Very interesting! For fun only!

.500 semi--325 gr Barnes X 2500 fps???

Another Runt cartridge!

MM - Runt

Now it is a good hour past my bed time! Hell it's already dark here, so gotta go, see you in the morning!

Michael

Here are the capacities listed...weighed and calculated for the 505/510 Gibbs.

Load from a Disk 173.96gr
AmmoGuide 162.3
My Jamison case 175.0
First Imp Iteration 180 - slightly improved

Second Imp Iteration 194.1 - improved to maximum case dimensions...3.15" COAL, 0.350" neck, -.630" shoulder OD, 0.050 shoulder radius...Just about as far out as you can go and still hold a bullet tight and get it out of the chamber...taper about equal to Robs 600 OK.

This one makes my mouth water for a single shot using a Savage LA and about as big as you can get using the "standard" bolt head and receiver...the next step is Ed's Sav 210 and the 50 BMG case or some specialized case...55 Boys AT, Russian 14.5x114 KPV...and I can always dream.

Luck with your toys

Re: .505 Gibbs gross water capacity:

That sounds like what I got measuring the Jamison .505 Gibbs case.
I still need to look it up, later to confirm your measure.
Jamison does not make thin brass.

.505 Gibbs: 175 to 180 grains
500 Jeffery: 155 to 160 grains
Depends on maker of case.

500 Mbogo: 155 grains ("There can be only one.")

Way, way back in one of Digest books offerings, an article was published including a list of case capacities. I used that list along with the "old" cardboard Powley calculator to work up approximate loads for many years.

The author also included a list of weights of cases from different brass makers of the same cartridge. He also showed there was always a variation in volumes from case to case and brand to brand. He admonished, pointedly, to be careful when using the data and ALWAYS pick one case brand, stick with it, don't mix brands, and measure 10 then average, to be sure...THEN...work up the load slowly. I have followed that advice these many years. Start low and work up slow.

Another good example is the 45-120 3.25" Sharps I did a couple years ago. Load from a disk listed 113 gr capacity, my Norma cases were 125 and TyKemp measure his at 132gr, don't know what brand he was using.

Quite a variation...

You also have the problem of the weigh scale. I have 4 digital and two balance beam scales and I got 6 different measurements from the the same case, empty and full. The two balance beam scales were the closest...no more than a few tenths grain difference, but I got a 4 grain range between the different digital scales. One scale wouldn't weigh the case the same twice in a row. In the fine print for that one it stated there could be up to a 5 grain variation depending on factors. So much for digital accuracy!!!!

One big lession I've learned over the years...there is NOTHING cast in stone in this endeavor and there are no "perfect" anythings. There is ALWAYS variation in all aspects and components.

I'm just very glad I have lots of choices and as technology advances, the ability to do things fairly easily today, that were very difficult in the past, just gets better.

Luck on your projects.

RIP THANKS!!! that was a lot of work, I appreciate it very much. I just found this thread, am going to go through real thorough, I love this kind of data. I owe you one.

Red

Dago red,
Welcome.
And thanks to you for the interesting idea.

My Jamison .505 Gibbs brass has gross water of 179.8 grains,
once fired.

FOOBAR,
You said 175 grains.
Was that new, unfired brass?
Lot-to-lot variation?
Either way, it is great brass.

Brand new, unfired brass...weighed 3 cases and averaged. The cases were very uniform to begin with and the variation wasn't enough to bother with so I just rounded it off to 175. It actualy averaged 175.2, I think.

Again it depends on the weight scale to a large extent, temperature, barometer reading etc. One grain of weight is a very small amount. Weigh a drop of water to see just the amount of variation that can be introduced by a tiny twitch at the wrong time.

The weight can also be affected slightly depending on the meniscus, if you have the curved "bubble" of water above or below the edge or if you siphon it off with a piece of tissue paper to level with the case top. One extra drop of water can swing the average one way or another by a few tenths.

In the real world small variations in case volume, powder weights or volumes, bullet weight and concentricity etc usually smooth out over time or shots. I'm long over nit picking and it only took one semester of statistics to realize some "truths".

If I were shooting for fame nowdays, I would use an air guage to measure the inside volume of the case and then pick out 5 or 10 of exactly the same volume, a Vern Juenke meter to measure my bullets, and an analytical scale to measure EVERYTHING weighable ...if you do that sort of thing you already know the drill.

No matter what a 505 Gibbs is a BIG case.

Luck on your projects.

Foobar,
You really should calibrate your scales.
Weight sets are made for calibration of electronic scales.
There is no excuse for error over 0.1 grain.
Also, for consistency, we must always use once-fired brass, and always, flat meniscus.
I have had two semesters of statistics, engineering and business statistics, and even some doctoral level statistics, not that it even matters.

From your new, unfired brass, and my once-fired brass, it seems there is no inconsistency, let alone any lot-to-lot variation.

You people need to get with it and start measuring once fired brass!
You gotta have a spent primer in the bottom of the brass to keep the water in!

You're right!!! Calibration is important.

You need to calibrate the scale you are using each time you use it...I do...I have a set of bit and pieces, "calibration devices", I've used for about 40 years that I made up and weighed on an analytical scale in the chem room the first chemistry class I took, and I use the calibration weights that came with each of the scales...but it is one of those unspoken, assumed things...I assume experienced people do the correct things the same as I do when I am developing loads...it is just something I don't hardly think about, just do...and you know what assuming does to people...

The problem is the variation or discrepancy BETWEEN different sets of scales and the fact that what you are doing isn't necessarily absolute measuring...you are just running a statistical analysis from and for a population...it really wouldn't matter all that much what the actual weight is, as long as the same scale is used for measuring the whole population...the weight variation will average out and would be the same within instumental error if you did the whole shebang with another scale, whether the two actually weighed the cases the same or not. If one scale weighed 2 gr or 5 gr higher or lower, adjusting out the error will give the same weight average. Again, to my way of thinking, is nitpicking for all intents and purposes except for those requiring that level of precision and accuracy. If that's where you're at, then do it and enjoy.

As I said, one scale I used had a large weight variation(instrumental error) that was inherent in the scale...not a lot you can do about that except undestand it is there and use it as a correction factor. Every "machine" has an inherent instrumental error that should be addressed if it is a significant point of error. But, I've learned over the years that some areas of pickyness just aren't worth MY time...everyone has different levels of pickyness tho'.

We could argue the difference between new and once fired cases...I ran several tests on just that question about 20 years ago using a benchrest 308 with a SAAMI minimum chamber, Norma and Rem brass...I trimmed, cleaned and uniformed the flash holes, uniformed the primer pockets, weigh sorted to get 25 cases each...at least I had to do that to most of the Rem cases...the Norma were almost perfect right from the gitgo. I don't have the actual data...or any of the other data of all the tests I've done over the years...a pissed off ex tossed almost all my "good" stuff.

The upshot was the difference between the fired and unfired Norma wasn't hardly enough to measure for all intents and purposes and real world significance to anyone but a hardened competition shooter bent on destroying anyone or anything that gets in the way of winning...the population produced a zero SD out to 4 places, the mean and mode were the same, and the range was basically zero...all the cases were lined up on one number, all the points of central tendency, for all intents and purposes, hovered around one small point.

There was a slight difference in actual case capacity between the fired and unfired Norma brass and a little more with the Rem, I can't remember any numbers now except that it wasn't very much. The rifle was a benchrester and the chamber was cut for Norma brass. The 25 Rem cases I used were already as close as I could get them and were in the same boat but weren't as close as the Norma brass...the difference came in the 100 unit population.

Again hardly any difference in a lot of 100 Norma, but a hell of a lot of difference in the lot of 100 Rem cases. As much as 10 gr range in case weights, 0.015" difference in case lengths, differences in shoulder "headspace" points and so forth. I always thought I was doing good to get 50 fairly uniform cases out of 100.

I just did a weight range for a bag of 50 Win 30-06 cases a few days ago for my "new" tang Ruger M77. It took weighing half the bag to get 10 within 3 gr. The range was over 6 gr as that is the number of sets of 0-9 numbers I have marked on my loading bench. I tossed 3 that were over and under those numbers. Unfired weighed 69 gr H2O, fired weighed 72 plus or minus a few tenths...I just rounded of to the next higher number if the scale was over 5 tenths and round down if under...Load from a Disk listed 66 point something. Not to bad a fit but I have to use a 0.008" shell holder which means the chamber is that much longer, but again not bad and the sizer only moves the base 0.001" so the case capacity increase comes from the longer length.

In actuality you are measuring the chamber volume of the rifle you're shooting when you use once fired cases and that is the information you want anyway...for load development. You can vary that volume depending on how the reamer is ground for a "standard" case/caliber Minimum or Maximum SAAMI or ??? or to define the volume you want if you are doing a wildcat...you know all this already but many don't...

I'm not preaching to the choir here...this information is for those that want to understand a little more of the complexity that may answer some of those questions of "why does this happen"

But, again, for hunting accuracy...especially for very large cases and the usual distances <100 yds...I don't get all that nitpicky. I ALWAYS uniform the primer pockets, do the flash holes, trim and weigh sort and most of the time turn the necks to about 70-75% cleanup of any caliber I do. For the price of a 505 Gibbs or even a Rigby case and what accuracy is expected I won't worry about a 5 grain variation in the least. I DO get more than a little picky when futzing around with my 17's or any varminters

I've figured out over time that about 90% increase in the accuracy of a rifle comes at about 10% futzing around, with the rifle and the ammo...and the other 10% increase in accuracy takes 90% very hard work most of the time...you have to determine for EACH rifle just how much of each is required and how much you want to pay in money or sweat equity for that extra 10%.

Understanding of these factors, the how's and where's of variation are usually the basis for all the BS arguments that go on all the time..."discussions" are always apples and kumquats because the impedimentors have different levels of undestanding and different requirements, views, wishes and wants. It would be nice if somehow everyone could get on the same page and stay there...just think how much knowledge and information would get spread around...instead of the other stuff.

I worked in QC for a while, have a AS in Quality Control and Tests and Measurements and have a few other AS and BS degrees, Biology, Psychology, Police science...I started in a Masters program at two different universities, but at 35 years old and having dodged a few baddies, it proved harder to handle the ignorance and BS associated with upper level studies and Profs than doing a 1000 yard creep or chasing some A.H. down a dark alley. It was easier to pick out the classes I wanted to take, individually, than deal with which and what is transferable and acceptable in what program and all those bright young minds sucking up trying to get the coveted "undergrad" position and by that time college degrees didn't mean a thing where I made my bread, and you were judged by completely different criteria. Plus I was married with a family to support...priorities are different for sure...

Today while I was chrono'ing some '06 loads I weighed a drop of water from the bottle I've been using for....on the Dillon scale I usually use...it registered 0.8 gr...plus/minus one drop can really mess with any analysis...hahahahahahah

Anyway....this business can be as simple or as complicated as you want it to be...that is what keeps it interesting...

Luck on your projects.

The first seven in the list will anchor anything you want to shoot and are capable of anchoring the shooter as well. My 500 Jeffrey can get a 570g Barnes going at 2400 fps with no signs of pressure, unfortunately I don't want to be behind it never mind in front of it. A leisurely 2100 fps with a 570g Barnes seems a reasonable load for us wussies ...

By the way, I thought the stock 500 Jeffrey load was a 535g bullet at 2400 fps.

It is but from a relatively long barre, 27" IIRC. From a typical hunting rifle barrel length it is closer to 2300 - 2350 fps. Again depending upon actual barrel length.
