.357/.454 bottleneck 5shooter??????

[shorty500]

Just an idea really at present not a definite plan yet! Have toyed with the idea of a .357 B&D several times and never seem to get around to building one, then the other night when researching some old articles for a friend i ran across an article on the LAR Grizzly Mags that had saved and re-read it. They offered a .357-.45WinMag years ago before that overgrown 1911 disappeared. And bang it came to me a friend had one once and i still have the die set because i loaded all his ammo. it was a Hoss for a .357 auto. Hmm!?!!?? wheels are turning! Hunted up the die set and necked a .454 hull to .357 and seated one of my 190g gas check slugs. i smell a 5shot Ruger Bisley in the works that will scream over the chrono! any thoughts anyone??

Too much time and too easy of access to the necessary tools! ;D

lol, not enough time to build everything that pops into my devious head. work a full time job as toolmaker/machinist in addition to doing gunsmithing & machine work in my shop at home. alot of the time relatively quick and simple projects for myself take months to get done

I attemted to make some 357 Auto Mag for a buddy about 30 years ago.... Tne parent case was the 308 winchester just like the 44 AMP.... Best I remember it was a very unpleasant process.

Reeder's stuff is good to look over when you are thinking of this stuff.. www.reedercustomguns.com/information/GNR_cartridges.htm

WHile he does a 41 necked to 358 for his 356 GNR for those who need more there is the 358 GNR :

Next up the ladder is our 358 GNR. This one is intended for big game and has taken a lot of it through the years. It is a 445 SuperMag necked down to 358 and comes very close to 35 Remington ballistics. Does well in stretch frame revolvers and in Contenders. Any 357 Mag or 357 Maximum Contender can be rechambered.

That idea of yours ought to fit in a standard cylinder, may not eve nneed a 5 shooter, maybe LEE could chime in on this one

If i am going to use a .454 hull then it will be a 5shot 17-4 stainless cylinder that way dont have to lose sleep over the chamber pressure- just work up good, accurate stuff that shows zero signs of excessive pressure and then let it rock on.
with an oversize 17-4 6holer it would be an OK round but with the case capacity that gain from the .454 cases would really need a 5shooter to reach the true potential of the round. otherwise wouldnt be much better than necking down the .45 Colt. even with an oversize cylinder dont need to drive a .45 chamber diameter much over 30k psi or you start pushing the limits.

Would the neck angle be too much for a sixgun? Just curious if you would get more setback problems with the larger case than you would from a smaller case due to the angles.......I'm a moron on bottleneck revolver cases so i'm just asking

By the way, I've got a few buddies from Ripley that I met when I was in school at Mississippi State a few years back....

never played with the bottlenecks much because like everyone else i have always heard that they won't work reliably much beyond the pressures of the old WCF blackpowder cartridges but as i grow older & hopefully wiser i read the rsults that Lee Martin & Gary Reeder have had with the higher pressures and we have seen functional .22Hornets, .218 Bees and now the .224-.327 from Freedom Arms so given proper chamber dimensions and clean chambers i believe it will work without alot of cussing

Doesn't Reeder build some big six shot guns on Redhawks?.... Seems like I read somewhere that the 429 GNR, 454 necked to 429, would work in a six shot Redhawk cylinder...

I believe (and may very well be wrong, so tkae this with a grain of salt, shot of Tequila. and a slice of lime) but I beleive those were for Super Redhawks

Gary Reeder's 429 GNR and 410 GNR can be built on the standard 6-shot Redhawk, only the cylinder is rechambered unless wants more done. I have Gary's 410 GNR (41X454) on a rechambered Redhawk 41 Mag. No problems with set back and 210 grain XTPs exit the muzzle at just under 1800 fps. Great Whitetail round. Loaded up with cast 255 grain LFNLBTs and I'm still getting 1550 fps for my black bear/hog hunting....RW

If you try to run that type of pressure, setback is going to be a big problem. That plus the 356 GNR/357 B&D is about as much as you can efficienty work through a 7 - 8" tube. Past that, you're burning a lot more powder for very little gain.

Redhawks and super redhawks are the same beasts when it comes to cylinders and the allowed pressures.

don't necessarily mean that want to run it @ the pressure of a .454 - want the 5 hole & 17-4 for absolute strength.actually even with the .454 case the case capacity will be limited with my heavy slug and will probably go with a 10" tube
