So, I keep seeing 357 mag blackhawks a few times a year for a song. You know the type, you have seen them too. They are in terrible shape, but really all they need is some TLC and someone willing to invest a little time and parts in them.
I have no interest in a 357 mag, I always pass. But it has me wondering about turning one into a 357 maximum, for the purpose of shooting DEWC bullets. I think it would be a neat little shooter. I'm not interested in loading 357 hammerheads to achieve the same thing.
But not too much chatter on doing something like this, but any thoughts?
Ditto on turning a 45 colt into a 460 wadcutter. Not loaded over 30 ksi obviously, but it would lend quite an oomph to a 45 colt wad cutter.

I like the idea. I go through 357s like you do. I buy them for a build cheap then let them go cheap. I happen to have one now.

I am not 100 percent sure, but I don’t think the frame window on a .357mag is large enough to accept a max cylinder. Ditto for the .45c and the .460.

Best to keep in mind that the wadcutter is a low velocity short range projectile, if you push them too fast, they won't stabilize properly & accuracy suffers considerably...Not exactly the purpose the Maximum was designed for.

I can't help but think the short throat in that cylinder would not be good for accuracy.

Definitely not an old model option... Maybe 360 DW?  New model maybe.  |

I'm pretty sure that if one were to use the hydraulic cylinder frame stretcher jig on a standard 357 mag blackhawk frame they may get a decent result  I'm joking if you are... If you do not have the cylinder length nor the psi potential of the 357 Maximum, what would be "maximum" about it? |

You guys are too serious. A 357 max chambered regular cylinder loaded with max brass containing trailboss and a flush mounted DEWC sounds fun to me. Sure you can do it other ways but we are not as a group a very practical bunch or we would only own 2 or 3 revolvers. The cylinder would still shoot everything it would before rechambering. Quality hard cast wadcutters are 50 yard accurate and a great small game bullet.

You have more than two or three revolvers? You gotta be kidding!
Sarcasm!

I will contribute to any project that ends with a 357 Maximum.
I've tried to collect some cylinder sizes for comparison.
US Arms Abilene 1.750"
S&W model 19 1.674 minus the recessed rim of .053 = 1.621"
S&W model 27 1.673
S&W model 13 1.625
S&W model 586 1.623
S&W model 686P 1.620 minus the recessed rim option
S&W model 60 1.590
Dan Wesson 715 1.640 minus the recessed rim option
Dan Wesson Pork 1.638
Ruger Sec Six 1.607
Ruger GP100 1.614
Ruger SP101 1.585
Ruger LCR ?
Ruger Blackhawk ?
Colt Python 1.560
Colt Trooper 1.555
Colt SAA 2nd Gen 1.606
Colt 3 5 7
Taurus M608 1.730
Taurus M66 1.580
EAA Bounty Hunter 1.760 minus the recessed rim option
Someone please measure your blackhawk and LCR for me and I'll edit the list.

What you are contemplating goes back over a hundred years when Smith & Wesson offered the .38-44 S&W. (NOT the .38-44 S&W Special) This cartridge was made for a .38 caliber No. 3 Top Break (Hence the ".38-44 designation ~ a .38 caliber made for a .44 caliber frame.) and the cartridge case was the same length as the cylinder, with the bullet seated entirely inside the case. Not a wadcutter but a round nose bullet, the idea was that the case supported the bullet until it jumped into the forcing cone of the barrel. This especially for target work.
There was also a .32-44 cartridge.
The only problem I see is having a gun that will chamber the .357 Maximum case in a revolver not built for it. But as long as the gun reads that it is chambered for the .357 Magnum, maybe no problem.
And further, from someone who remembers way back, there were some .38 Long Colt revolvers which it was found would chamber the .357 Magnum. And some of these were disasssembled violent!

Might not be the easiest option but if the OAL is close in a mid frame .357 cylinder can't ya' just trim a little off the max case to buy you the difference so you don't have to seat the bullet flush to the case mouth?

Bob, a Max case with a regular seated bullet would never chamber before the nose of the bullet hit the ERH.
