Blackhawk in .32-20?

Thanks Brad I guess I should have checked GB. I have a New Model Blackhawk in .357 mag that is nothing special. I have better guns to shoot .38/.357 in. I was entertaining the idea of (a) making a new cylinder and chambering it in a smaller caliber (.32 or smaller) or using the existing cylinder and going to a larger caliber. I don't want to duplicate anything that is a commonly available factory offering. I've thought about .32-20 or .32 Mag, .40 S&W, 10mm Auto, .41 Special or .44-40.

Any thoughts?

I have a 357 BH like that too. Mine was purchased new with a leaded bore. I cleaned out the lead to discover a ring in the barrel at the end of the frame. I think it was a cowboy action gun and got fired with a squib stuck in the bore.

A 32-20 would be nice if the throats and barrel match. A 32 Federal would work too, a 32 H&R would be a bit small in a BH.

Now a 41 special, that would be nice. Or a 38-40 with the right dimensions.

The full sized Blackhawk was made in twin cylinders 38 WCF and 10 MM at one time. I always thought that it was a good combination, one for cast and one for jacketed. The FBI agent who headed the 10 MM project for them retired to a ranch out side of my little town. He had nothing but praise for the cartridge with full loads. Said it was good for 400 pound drug runners or mule deer. 38/40 is always a fun plinker.

Long ago they did a convertible in an opitional 38-40 , and I think 10mm/40 .
I always thought I'd like to have had that pair/trio . I think it only ran a yr or so .

At large, whereabouts unknown.
The 32-20/32 H&R convertible Blackhawk, and the 38-40/10mm version were specially made for Buckeye Sports in Canton Ohio, and are pretty highly valued nowdays. Maybe Lipseys would consider a re-issue in stainless, so as not to jeopardize the collectors values of the Buckeye editions?

Failing that, a 30 Carbine BH can be brightened up considerably with a rechamber to 30 Paxton, however the barrel twist is a bit on the lazy side for bullets much heavier than 110 gr. The dies are horrendously expensive as well. Perhaps a wildcat cased on the 357 mag or a shortened 357 Max case sized down in a 300 Blackout die? I'd have to check out the chamber dimensions at the base of 300BO vs. the 357 cases.

Keith, why not a simple 44 special? I know you have a fondness for the cartridge. It just makes sense.
Make it a special gun for yourself.
My 357 will likely end up a 44 special.

I have had my buckeye 32-20/32 HR for several years.
Prior to that I had played with the 30-20 in a Contender and a BF for close to 20 years.
I don't feel I have hotrodded it at all. More like bringing it up to date much like the 45-70 and 45 colt.
I can get a 140 running about 1500 fps and change out of the buckeye.
I ran that load for IHMSA BB, 50-200 meters. I scratched out around a 30 or so as I recall.
It's bark is worse than its bite. Much like a 30 carbine.

If you are going to go this custom route, might as well do a convertible 44 SPC/44 WCF! 2 cylinders and set it up to shoot .430 cast ( I have a Uberti 44 WCF that shoots .430s).

they done a 40 short and 38-40 I had one, my dad had one, one number away, he has them both now.

the 30 carbine Blackhawks are super easy to make into 32-20's.
just trim 32-20 brass down to fit the cylinders and shoot, then use 32-20 dies and 312 diameter bullets to load.

My 30 carbine BH has really tight throats. I had to polish them a bit to get them to take a .309 bullet. Even now I size to .308 for the gun.

I remember reading at some point about a 7mm/.30 carbine wildcat that sounded interesting. How come there are no handgun calibers between .22 and .32?

A 25-20? Would be an interesting choice. Recoil would be non existent but plugs and muffs would be wise.

Has there ever been a revolver chambered in .25-20? I wouldn't want to run into .22 Jet/cartridge setback problems.

A little Google work and I find hpthat Bowen made some 25-20 revolvers. I have a feeling Bowen wouldn't do it if it had setback issues.
Taurus makes a Raging Hornet revolver in 22 Hornet and it has a far more shallow shoulder than a 25-20.
I think the 22 jet was a problem because it had a huge, tapered shoulder. A 38 necked to 22 needs a bunch of taper. I wonder if a sharper shoulder would reduce the issue?

How hard would it be to model the set back on a computer? I would think that someone with the right system could calculate back thrust.

Not being an engineer I may be off base but I gotta think it would be possible.

What about a 256 Win mag ? A necked 357 to .257 .
Seems like I read something about set back but they don't seem to have that with the 5.7 .......but it's all autos ......
