Thanks for the kind words Prof! I really enjoy contributing to any of these projects however I can.

Don't let the soft exterior fool ya' though! I'm really an elitist mad scientist with delusions of global projectile domination.

most successful people started out with delusions of grandeur and then acted upon it.

What in tarnation do you own in 475 Canuck!?!?

Sheesh....how long you been hangin around here anyway? A 470 Mbogo of course!!

Check out www.470mbogo.com.

Sorry Man! I forgot all about that beasty!

I suppose I could add something suitable for the 470 Mbogo. What kind of weight would you need boss?

Well, anything between 500 and 550 grains with a nice fat meplat would be just dandy.

I do prefer the 530 to 550 grain range for th .475, but heck, I am not fussy. 500 grain solids work pretty good too...I used some 500gr Bridger FNs on cape buffalo with great results.

I have a 475 Gibbs reamer here somewhere, and a Krieger barrel, and RNS brass, and, and, and...make it a 550gr if possible.

Knowledge not shared is knowledge lost...

Here is my data for the .505 Gibbs with 558-grain S&H Brass Grooved FN solid:

three shot averages for velocity:

H4831:
120.0 gr >>> 1810.3 fps
125.0 gr >>> 1899.7 fps
130.0 gr >>> 2041.3 fps
132.5 gr >>> 2100.7 fps
135.0 gr >>> 2174.0 fps
137.5 gr >>> 2238.0 fps
140.0 gr >>> 2307.2 fps

First 5 three-shot groups were used to get on target with 2.5X scope at 50-yards, and as velocity went up the rifle shot lower (less barrel time during muzzle rise), windage no change. The final scope adjustment is shown below, with the best group being the 137.5-grain load that fills the case completely without compression.

Target shows more info:



My H4831 is a bit slower than I expected. RL-15 or Varget with Dacron would kick less for same velocity, maybe as good or better accuracy?
Maybe why Nickudu prefers RL-15?

OK...you've talked me into it. Hopefully we've talked Macifej into it!

Excellent work again Doc!

Seems that the old 505 is quite capable out to 100 with the H4831 load. Tsbindi used this bullet with about 110 grains of RL15 for about 2175 fps.

Does anyone else have a 2200 FPS load for the 505??

Check back here about noon Idaho time for a report with more AA3100 and the N160/165. I had not tested for accuracy trying to make sure I did not "rear-end" any of the bullets. We will do that Monday.

So, what about a 625gr .550"?

Mac,
Sorry I did not do any better with the accuracy.
You can see I was getting a flinch at the end there, flinching downward.

By switching to RL-15, I might get about 5 ft-lbs less recoil energy and about 1 fps slower recoil velocity. That might allow me to tighten up the groups.

I'm thinking 115 to 120 grains of RL-15 or Varget Extreme plus 4 to 5 grains of Dacron filler might be the magic 2300 fps accuracy load with your bullet.

Rich,

I can do the 625 grain 550's soon. How many of those can you guys use in one shot?

RIP,

I think guys who try to make a Clydesdale run like a Thoroughbred are either misguided or perfectionistic eh! The magic load is out there somewhere it just needs to be found by someone with a rubber shoulder and a cement head!

Cement shoulders and rubber heads work well for this activity also.

Rich,
Rubber head and cement shoulder, or cement head and rubber shoulder? In your expert opinion, what makes for better accuracy with a .505 Gibbs?

Maybe snorting a bottle of rubber cement before either could have an aneasthetic effect?

I just finished a half pint of Schwepps Tonic laced with two shots of Bombay, a shot of Unicum, and a spoonful of Orange Metamucil mixed in. A couple of Advil PM's and am ready to shot whatever the hell you guys can come up with!

I'll see what I can do for ya' Canuck!

H4350 could be the answer!

Forget the slow stuff.

Forget the fill fluff.

H4350!!!

A 475 500 grain flat nose should go from moo'er to tooter faster than taco bell...500 is all ya need.

You say that like you've shot stuff with it.

Hey, ribbing aside, you're all hyped on SD...the 540 to 550gr .475 would have the same or a little better SD than a 500gr .458.

470Mbogo (Dave) has some of the limited run of 540gr Bridger solids with a .410 meplate. He loves them in his 470....Macifej, if you'd like one of these to work from, I am sure Dave and I could arrange to get you one??

Cheers,
Canuck

In some fragmented semblance of order:

1. RIP, me being a disabled vet, and you having some clout with the VA medical system; I was hoping you could
get me some scrip for a couple syringes and about 4 hours worth of a strong local anesthesia...by 8am Monday

2. Macifej, IMHO which is just and only that; a 500gr .475" solid would be perfect.

3. RIP: cement head and rubber shoulder. Seriously, the recoil reduction system I am testing works great. No
pain or bruising to date, shot all twelve rounds last trip out.

4. Boomie: Along that line, if I can get the digital camera to focus down for me after church, I will send you
some pictures tomorrow to post.

To give some perspective on how good these bullets are, my first three shots the other day were my hardcast
(Bhn 24) heat treated 650gr GC cast bullets. The heaviest fragment I found weighed 164 grains. The farthest penetrating fragment was found 5 1/2" into the first bag. Wet sand will test a bullet for construction and deformation resistance like nothing else.

Canuck...I have not been to the moon but I know it aint swiss cheese...

In yer 470 mbogo a flat nose non deforming solid of .317 S.D. should tear up a buff...

Any armchair balistician keyboard PH knows that!

When my 470 is done I could play with them 470's...We have a 500 grain mold for cast bullets already.

Canuck,

I work in a Vacuum Locked Ivory Tower and wouldn't want to be seen "borrowing" someone elses design.

I'll make the 475's and the 550's for you guys ASAP. If you guys want to speed up the process, get five guys who will consume 100 bullets each. The minimum run I can do and cover the cost of programming and tooling is 500 pieces. 1000 piece runs make them a little cheaper.

What is the cost of 100 out of the 500 of the 475's???

We should be able to pull that off...quite a few 470 users and soon-to-be users around here that may be interested. (470Mbogo?, RIP?, IdahoSS?, Jeffe?, Boomie?, Robgunbuilder?, Canuck32?, etc, come quickly to mind)

I'll do some investigating...approximate price point would be useful info for gauging interest.

ps: If you are doing a run of .510's, I'd be interested....need to feed my A-square.

Cheers,
Canuck

Canuck, I think Rich is talking about doing a .550" slug for his artillary piece AND a .475" with you.

So far I have guys who have asked for:

.375

.395

.416

.458

.475

.505

.550

Anything else while we're at it?!?

Maybe Someone should put together a pole for who wants what and what weight.

I just want to say how cool it is that we have our own in house bulletmaker in macifej...Thank you!

pps: it occured to me that these "shorty" 470 guys (ie. 470 AR) might be worried about filling the case with too much boolit...if that's the case, and the majority prefers a 500gr .475 solid, I can live with that (although I would prefer something a little heavier).

Cheers,
Canuck

poll???

hey, maybe Mr Tunbull might want some light weight ones in his 475 Turnbull

I will need some in .500" once the 500 max is up and running.

Also some 50 Alaskaners and 50 Kodiak Expressers might want in.

I read it that he was going to make a 475 Gibbs and preffered a 550gr bullet for it.



Whatever...no biggie...

About $275.00 per hundred. Shipped via DHL to anywhere in the CONUS. Have to check the rates to far flung Canadian and Alaskan Villages as the shipping might cost more than the product.

thanks for looking out for the shorties

Monometals are long enough to be going over .317 S.D.

I will have to go in with five other guys for 20 apiece to help out with 1/5th

Who else here has beer taste and a tapwater budget?

US address makes it very easy.

Reread the earlier post. Have to ask Rich why he changed his mind on the weight. He may have had a calculator in front of him and decided shorter was better.

I can make anything you guys want if you can order the minimum.
