Wow I was so busy I almost missed this post. I should get busier.

Ron thanks for the fair mention and best of luck with your adaptation. I just didn't find it necessary with the 470 performance.

Canuck and Gatehouse you guys crack me up. We should all go shooting this spring. I'll bring the beer and it will be fun.

Take good care,

Dave,

thanks for the clarification on the design. It's good enough for me.

rip-off,
you pathetic dungheap for a throne king of the liars and misappropriators. You set a date after September 1st and give me an address where you will be hiding and I'll be there. Got an open invite from my brother in StL to come to a cardinals game.
We need somebody from here who lives in your area so that we have a witness to you not being in the same time zone when I show up.

Just let me know, unlike you I am not too broke to make the trip, and my cartridges are not computer drawings, they are brass...formed, loaded, and fired from real rifles I own and shoot. So stick close to that crack pipe and keep finding those substitutes for reality. Pencil-necked geek.

Dave,
Thanks for the kind words.
The design is as it should be, and called as it should be, with your approval now, and the very same idea you mentioned here years ago:
500 MBOGO

Kevin Jenkins knows that it is next on the work schedule. I'll deliver the parts to him shortly. I have everything except the sight parts, which he will order.

If Stuart Satterlee ever gets the stainless magnum Mauser action ready, there could be another 500 Mbogo in the world. The first will be one of those Czech-made actions.

Too bad such a foul flatulence has polluted this thread, and the source of this rotten egg smell thinks the 500 Mbogo owes fealty to his .510 keester express.
Very strange.

Best Regards,
Ron

Normally I wouldn't lower my standards to hang out with an Easterner like Canuck, but since I saw your stats, I will make an exception, because you and I and a beanpole like Canuck would make one hilarious photo op. Cool

Macifej,
A potential market for your 2-Bore was suggested by this page from Ken Howell. Plastic bullets to use as polar bear persuaders in those polar Canadian villages:


I suppose I could whip up some low pressure load and hollow plastic slugs filled with "Bear Spray". Have to fill the case with about 3/4 capacity wad and some blue dot. I already had some Yahoo from up on the north slope who wanted me to build him a rifle for "Cabin Defense". He states that there is a particular bear in his 'hood that had repeatedly tried to push over his house and eat him. I explained that he would already be dead from the 700 grains of 3F shock wave, smoke, and subsequent conflagration when fired indoors and didn't need to worry about the bear. I offered to design him a bear proof cabin and send him a bear fogger. No reply. Razzer

rip-off,

more likely me thinks you owe a big apology and homage to John Buhmiller who had invented the basic 50 on the 416 Rigby case, built the rifle and reloading dies, and shot elephants with it before you got out of friggin diapers. Of course your senile approach here suggests that you transitioned to depends not too long ago. You lie about every post when you say you have me on ignore and then babble on about what I post. So, you have no honor, and you are a liar and a thief, a plagiarist at best.

Read this and pay homage where it is due: John Buhmiller in the 1950's built what you would like to claim as an original idea, the 500 Magnum on a 416 Rigby case. I quote: "...I also made another wildcat using the 570-grain .510" diameter bullet that is made for the .500 (3") NItro Express double rifle(on the Rigby case)...and 90-grains of 3031 was OK in the 50. This article was written by John Buhmiller and published in the May-June first issue of Handloader Magazine. It described his early experiences hunting dangerous game in Africa along the Rift.

Get it into your pea brain, there certainly seems to be plenty of room there. Half a century ago, John Buhmiller built a 500 M'bogo and shot M'bogo with it. You and anyone else doing one now are just riding on his coattails and trying to take credit for something someone did a long time ago. You fail to understand that your' thinking about something is NOT the same as doing it. It's like thinking about buying a lottery ticket, even if you thought about the same six numbers they drew; they are going to give all that money to the person who actually paid a dollar and bought that ticket. Get over it!! Thinking or fantasizing about it IS NOT! the same as actually doing something! Dim wit!

Rich

Gatehouse,
Ouch! You quoted him!
His imagined slight for my not kissing his .510 keester express has now switched to me having wronged John Buhmiller, whom I admire greatly.

Who the hell ever said that the 500 Mbogo was the first .510 caliber cartridge of Rigby proportions?

I have read and filed articles on Buhmiller and P.O. Ackley has a great chapter by him.

How about if I use a rebated (two-diameter) lead 50-cal bullet on a blown out H&H case and call it the 500 Buhmiller Zephyr and dedicate that one to John Buhmiller? Would that shut him up?

The Idaho Zephyr is On Ignore. If he wants me to listen to his crap he will have to make me ... and it is going to be tough explaining to the investigating officer why I had to "subdue" him ... "You see, this guy in Idaho was getting special messages from innerspace (corncob vibrating in Morse Code) telling him to defend the honor of John Buhmiller ..."

I don't get it myself. What will the judge think? bewildered

Macifej,
I would like to challenge the Idaho Zephyr to a Habenero eating and Ratzeputz drinking contest.
I'll put him under the table in no time.
It would also probably dislodge the corncob and put an end to his vibratory hallucinations, hopefully curing his psychosis. beer

Being the underpaid witch doctor that you are...surely you know the ramifications of said competition. I would bet that the both of you are familiar with the known side affects of Capsicum chinense

However, it is unlikely that either of you truly comprehend the magnitude of horror that this particular Prussian "Delight" will inflict.

The French gave up Alsace for fear the Germanic Alsatians would call upon their lower Saxon brothers to reinforce them with barrels of Ratzeputz. Even Schwabians and Bavarians fear Saxons while they are under the spell of the Ratzeputz. Cool

HI Gatehouse
I already had a photo taken like that standing between Canuck and Canuck32. It sort of looked like a half filled sandwich. Canuck32 is is 6'7" and 370lbs. I keep drinking beer but it just ain't happening. My eye sight is getting worse and I keep getting skinnier. I better check into a Holiday Inn Express and get this figured out. Oh Ya I'll extend the front of my trigger guard so you can get your finger in to shoot it.
Take good care,
Dave

Well,. I can't compete with 6 7" and 370..Outa my league. I'm big, but not a giant!! Cool

But that is waht INTELLIGENT people do- they KNOW thier LIMITATIONS... Intelligence is not for this thread Razzer

Thanks for enlarging the trigger guard for me, even though I am somewhat of an imp compared to him, I still have big hands.

not invited to drink beer in Canada...now my life truly has no meaning... #4 son crack open that Glenlivet and let me drown my sorrows.

Looks like the group that woofs a lot has memory short enough to compare with their penis lengths.

But I am content, rip-off has finally had to acknowledge John Buhmiller and his contributions to wildcats in .45/.475/.500 of a half-century ago. I guess that's as much of an admission of omission as one could reasonably expect from some junior kin-tuck.

It does concern me that rip-off has this fetish for sticking things in his anal cavity, that's generally where comments of such a nature arise. Were you sexually abused by a parent or other family member as a child? You talk of anal penetration with foreign objects with such a casual familiarity, has it been part of your sexual self-image for a long time? It's a tendency to project our own insecurities on those who thwart us in significant areas. A simple analogy would be the pot calling the kettle black, because that is the pot's self-image. The pot cannot cleanse itself of the black, so it projects that inner self-image onto others.

Freud delivered a thesis in Furth (umlaut over the U) in the early 'thirties, where he suggested that most inappropriate adult behaviours are as a result of childhood sexual trauma. A person like rip-off who may have been sodomized by a parent or other family member would still want the love of that parent or other person; so they model that love in terms of anal contact. It's the same line of reasoning that men who abuse their children use as a rationale. They cannot live as a child believing that the person who loves them (which is what they have to believe to live) would do this (administer savage beatings on a regular basis) unless it was a sign of love and affirmation. So, down the road, they marry and father children...as those children grow up; the parent abuses them as a twisted way of showing love and using the facade of disciplining a perceived unruly child. It is a vicious and endless cycle, that only today are women being trained to report the abusive situation early on. Of cours, those same men who were abused often saw their fathers abuse their mothers as well, so the entire family unit needs to model proper familial obligations and attitudes. It is hard, and I have seen family units need years of counseling to work thru the issues of childhood.

I'm sorry to deliver such a lengthy dissertation. I printed out all of rip-off's diatribes and shared them with a friend from the APGCA (American Psychologists & Guidance Counselors Assn). Her first question was: "is this person successful in some business...?". I told her that the posts indicated that and her brief assessment was that there was some deep-rooted trauma and that the person likely went off on me due to a perceived threat or competition. The rest is all supposition, based on the posts. She did suggest that rip-off's perception of me was as a threat to his emotional well-being and his perceived status in the group (AR forum). Especially the issue RGB brought up in jest about a physical confrontation as a means of settling the conflict. In some meaningful way I pose a threat to rip-off here, and the physical situation where his physical side might suffer the same ignoble beating that his psyche is undergoing here might pose a meltdown of some sort.

I would hate to be the cause of a nervous breakdown for anybody...

So, rip-off I am hereby offering you a way out...never mention my name or refer to me in any sort of unflattering terms AGAIN and I will let you slide. You can rationalize, privately (in person, on the phone, or via Email) or in PMs here about me. If, on the other hand, you make any more comments here that you wouldn't make to my face, I will track you down and give you that chance with the bat. ONE MORE RUDE COMMENT!

To the forum: this is the best I can do. All of you here understand that the internet is the only place where a
person can call another person names and (believe) there are no consequences for their actions. I am here to tell you all, that that is not the truth. We can all talk here, and agree or disagree. I am not here for approbation, just to learn a few things and share a little of the knowledge I have been given over the years.

I do admire Dave Estergaard for the modern work he is doing with the Rigby case, and how his talents as a machinist and gunsmith have made the work begun by others, such as John Buhmiller, A&M Rifle co., Fred Barnes, and Fred Wells more widely known and rifles for those cartridges made available to more people. The internet is an endless stream of knowledge and the perfect forum for the interchange of that knowledge. JeffeOsso is another prime example of a "doer" who does, and reports his findings to all of us here. There are others.

So that's the deal...

regards to all,


Rich

Gatehouse,

you disappoint me...substitute the name Gatehouse for mine in rip-off's diatribe the past week and tell me how close to kentucky you would be in your rig? Maybe an hour out?

Conflict is the way of the world. Her comments centered around the fact that rip-off is making these statements on the internet in lieu of to my face, and throwing up the defense that he is impoverished and can't afford the plane ticket to Vegas as RGB so nicely suggested. little rippy, you see, is NEVER going to face me unless I show up at his house, and he cannot detect who it is in time to run back inside, lock the doors and dial 911. I figure if I called you out like I have the cretin you'd be here by now. SW Idaho is not that far away. You might look closer at see the crybaby for what he is...got an alligator internet mouth, and a real world hummingbird ass. He has spent the past day or so crawfishing as far away from a face-to-face as he can and still maintain some face here.

As far as my red-headed psychologist ex-roomie (pisses my wife off EVERY time she calls or Emails) told me that was one of the things that attracted her to me long ago...probably one of your main attractions to the 22-year old you are seeing now. That raw animal aura that a powerful, self-confident man gives off. She also said that the fact that she classified me as a mild psychopath and devoid of mercy in conflicts was a tremendous turn-on.
If I may stray afield a little, Hemingway wrote that men he met that had hunted other men for a living had a certain animus. Spend just a little too much time in the business and human life, especially any perceived threat has no real value. It's like getting into a bar brawl. Most people will stop pummeling someone when the antagonist stops being a threat, or submits...some people won't. I have been a no-limits kind of guy since about halfway thru my first tour of duty in the 'nam. Killing people is no diffferent than wringing a chicken's neck out on the ranch, or slaughtering cattle in the winter...kill them, butcher them, and haul the carcass parts to the processor in town. I don't consider myself a particularly psychopathic individual. Things just don't bother me at all, is all. The VA shrinks worry more about me than I do. I'd just make sure it was worth while to me.

have a nice day, we are here.

I am a joy-filled soul about 90% of the time. Sometimes it just doesn't take much stupid in the bag to set me off.
Sheesh, I got a really fine wife, social worker by training and work to understand how to deal with me. It's an occasional night with PTSD, that's all. I spent the afternoon making paper fighter planes with three of the boys, and hammering a six pound bag of gummie bears. Then I worked on the windmill awhile. I havent really hurt anybody in years...I think.

PS: not to worry, this little tiff is just amusing...
besides, ask your doctor. Crazy people who aren't confined are the happiest folks in the world.
I do appreciate your concern, but I'm just fine...

It would truly be best, before this escalates into a loss of liberty for anyone involved, especially the right to own a gun, that Rich Keyser and Ron Berry totally ignore each other. Anyone here is free to use the Ignore Function.

Back to the original topic of this highjacked thread:

470 Mbogo (2.945" with .415" neck length) case capacity: gross water = 143.24 grains

500 Mbogo (3.000" with .492" neck length) case capacity: gross water = 150.16 grains.

Just a little shy of the 500 Schuler/Jeffery.

I would like to see the 500 Mbogo do 2500 fps with a 570-grain bullet, GSC FN and HV.

Do it with a 10" or 12" twist and it might even handle the Barnes TSX 570-grainer and brass solid if that is all one has to plink with.

Woodleighs or Barnes Originals of 570 to 600 grains should be no problem to get up to 2500 fps.

10" or 12 " twist would do fine with the 50 BMG bullets up to 750-grains at about 2200 fps in a 24" barrel.

I have not run this through AccuLoad3 yet, just guessing from my experience with the 500A2.

I'll try AccuLoad3 with:

.510 caliber GSC FN
570-grain bullet weight
Bullet length = 1.405"
case length = 2.990" (trimmed) or 3.000" max
max COAL = 3.750"
24" barrel
gross case volume = 150.16 grains of water (3.000") or 149.64 grains at 2.990" trim-to
(.510 caliber bullet water displacement = 51.66 grains per inch)
Max average pressure allowed: a comfortable 60,000 psi

I'll run those numbers and see if anyone else (with QuickLoad?) generates something different from AccuLoad3.

I think there are no bolt thrust restrictions on the 500 Mbogo in a CZ 550 Magnum: The brass is still the limitation.

60,000 psi should be easy enough on Norma, Federal or Jamison brass.

Since CZ550 action is your likely candidate look at the following logic here:

Action LIKELY has a safety factor for high pressure loads (over 70,000 PSI)

Given that - lugs are LIKELY not an issue.

Given that - the action is already chambered for obese cartridges at decent pressures such as the .505 - shank diameter (which is fixed at a maximum) is OK for these fattys the key being the FACTORY barrel material strength.

SOOOOOOOO.......the only issue that I might be concerned with if I was making said device would be the quality and strength of the AFTERMARKET barrel with the little shank that you are installing.

Solution - know your material and calculate hoop and radial stresses, account for any perpendicular axial load from light weight action and give yourself a big fat safety factor. Hint - 4140 annealed bar stock from Bubbas barrel company doesn't afford much of a safety factor for accidents or negligence. This, of course, is just the opinion of an out of work circus clown.

Macifej,
Those CZ .505 Gibbs are stamped on the barrel with torr pressure limit that is equivalent to about 55,000 psi.

I figure the same action with the smaller .416 Rigby case head is good to 75,000 psi max average pressure.

My barrel is a McGowen stainless 10" twist.

I noticed that the fastest twist offered in .510 caliber now is 12" by the new McGowen Precision Barrels, LLC.
CRYBABY

I have no worries with my barrel.
Hey, this is just a 500 A2 with a slightly roomier case, hence lower pressure case for same performance. thumb

Forward the material specs for your new barrel (tensile, yield, & RC hardness), chamber/case diameter at the rim, and shank diameter and let the Maci take a sniff! Stinky Salmon or Beautiful Blueberries. (I'm sure it looks good but overly analytical Macik want to know)

FYI - Pac-Nor does a 1:9 twist and Bartlein Barrels uses a CNC rifler which will do any twist you want. (no cams or bars etc)

Hey man! You are getting too complicated for me. After a dozen of his barrels, including 2 500A2/.510JABs, I have faith in Harry McGowen. He was only 76 or 77 when he made this one, afterall. Wink

I wasn't inferring that Mr. McGowan doesn't make a fine product - only that I was curious about the safety factor in most of these new rifles (for my own amusement). But it's OK I know when I'm not wanted Frowner

Did I tell you about the time a local guy was teaching himself re-loadin' and packed his 8x57 cases to the top with some Power Pistol or Blue Dot or something and then compressed it with a projectile?!?!? I didn't know that M98's would peel open like a bananna! Cool

Just say Kayser, and we can call it good. I'm not going to put you on ignore, you contribute waaaaaay too much good thought and application to this forum. Take your .395 wildcat on the 375R. Great concept, and you are backing your play with your own $$$. I can bury the hatchet without using your forehead for a final resting spot.

Not me. I've got better things to do than track down people that insult me on the internet... also don't really care what someone that I have never met-and will never meet- think of me. Smiler

Plus, I'd be spending my whole life fighting internet battles, and seeing as I mostly hang out on shooting sites, eventually someone is going ot get shot for no good reason. Wink

On another site, someone photoshopped a picture of my face on to a freaky looking body wearing a pink tutu. Its actually a pretty good photoshop.

It's been circulating for years and it pops up every now and then...Now, this picture is VERY insulting but it's also damn funny. If I was to track down everyone that posts it I'd never get any sleep.

While I can get into knock down debates, in the end, the internet forums are just not to be taken so seriously that peopel come to blows.

The intraweb is way more fun if you don't sweat the small stuff. Smiler

Gatehouse,
You are a big man in more ways than one.
I am so glad you did not decide to post the pink tutu picture here to prove how thick your skin is. lol

Gatehouse,

this is getting "...curiouser and curiouser..." to quote a book I once read.

You really do mean to tell me you are ok with people talking trash to you on the internet?

I grew up on a farm across the river a little ways from St Louis in the fifties and sixties. My dad farmed and milked 240 head of guernseys and worked in one of those mills, and my grandparents had a small JI Case dealership. Busy days. The town nearest to us had four steel mills and the support system for them. An awful lot of the men working in those mills were second and third generation what we called "Bohunks", immigres from the slavic part of eastern europe. They were hard workers, they came to America to build a better life for their families. A lot of them were built like you.
They often didn't have a lot, but they were proud of themselves and what they did for a living. Their kids went to school where I did, and they did NOT! allow people to talk trash to them. There were fights every day at school in Jr High and High School, over real or fancied personal slights. Some of my best friends, and toughest fights were with these kids. If you had a friend, you had a friend for life.

Let me give you an illustration: I rode my Panhead down to a bar called Boschkoff's, good third gen "rooskies" who left Russia in 1916-21 because they had an idea what communism really was. The old man Sam, had retired on disability from the mill and bought a bar. Family place, and you might see the catholic priest there of an evening enjoying a beer with his parishioners. My dad made foreman a couple years earlier, and he fired a classmate of mine earlier that Friday for being a slacker. Soooo, me and a partner named Tom; we cruise in to Sam's for a cold one or ten. This guy Jakich and two of his friends are down drowning their sorrows and bad-mouthing my Father to the assembly. We walk in and he starts telling what a no-good SOB my Father is and what he'll do next time he sees him. I didn't know any of this right away, so I get a quick update. I've always had that clan heart, and I told him I had the folks phone number memorized and that if he had a dime, I'd make the call and he could back his mouth with a stomping if he had it in him.

He yaps around a while and I told him I'd stand in for my Father, since it was pretty clear he didn't have the balls for a set to with "Big Ed". He and his two friends decide to make it a party. About that time Tom tells the two guys that he'll do the steel mill waltz on them if they interfere. It's a quaint little euphemism for taking your steel-toed boots to somebody's head when they hit the floor. Tom, now, he's got a little of a reputation around the foundry floor as a man who will do what he says. So, me and "Jake" we have us a little set to... It turns he wasn't up to the task. My partner Tom was 5'11" and about 170, but neither of these guys at at least 6'1" and 230+ wanted any of part him, even two on one.

That's how I grew up, you do NOT take a nickel's worth of crap from anybody over anything... You have to be man enough to admit it if you are wrong, but I never yet took one step backwards for anybody. Not in school, not in the Army, and not since... I got my butt kicked a couple times, but the guy always looked as if I got my money's worth too. And, I always went back for a second shot the next day. Y'see honor is the most important part of a man, you let somebody take that from you, or give the appearance of having done so... nobody I know figures you for much of a man anymore.

Things must be different where you come from...


regards,


Rich

AccuLoad3 fails to compute: bewildered

Maybe I have buggered something somewhere?
I would appreciate if someone could run this through QuickLoad or other program:

.510 caliber
570-grain bullet weight
Bullet length = 1.405"
case length = 2.990" (trimmed) or 3.000" max
max COAL = 3.750"
24" barrel
gross case volume = 150.16 grains of water (3.000") or 149.64 grains at 2.990" trim-to
(.510 caliber bullet water displacement = 51.66 grains per inch)
Max average pressure allowed: a comfortable 60,000 psi

Thanks in advance for any daring soul who helps to further thumbunderstanding of the 500 Mbogo.

BTW,
Stuart Satterlee is alive and well. Maybe this will be done on a Satterlee Stainless Magnum Mauser, sometime by Aught-Eight?
