Obviously you can buy brass 410 shotgun shells. CH is offering reloading dies. So you can use this brass case to make a normal revolver cartridge. But the inside diameter of a 410 brass shell has got to be no bigger than 0.430. And the diameter of a 45 ACP or 45 Colt bullet is 0.451. So what would be a good bullet to use here?

What advantage is there to using a .410 case over using a .45 Colt case. None.
 
Since they already make reliable slug loads for the .410, I guess I don't see an urgent need to reload with brass cases. Would think that shooting slugs out of a Governor, Judge or Bond Arms derringer wouldn't be a high volume evolution to justify the effort. But, just my opinion, this shouldn't be interpreted as a put down, it's not intended to be. Don
 
There has got to be one heck of a long freebore using a .45 LC in a chamber long enough for a .410 shell. If you could get a long brass case that would still hold a .45 bullet it could be a big advantage but you would be all on your own as to safe loads. Maybe with these guns becoming popular someone will come out with a commercial long cartridge.

Freebore isn't gonna make a difference at self defense ranges. That's the intended purpose of this weapon. If you shoot someone at the distance where freebore is affecting your accuracy, you're probably going to jail......
 
I just read the other day of a specialty company making a heavy lead slug (186 grains if I remember right) for the 410 that equals a 44 mag in muzzle energy. Having a marlin lever in 410 -- it was of interest. Also of interest was it could be properly loaded in a 2 1/2 or 3 inch case. Should work fine in a judge handgun.
 
I would imagine that the brass thickness in the head is thinner than a regular handgun cartridge. Shotgun shell pressure only runs 10,000 to 12,000 psi while most handgun cartridges are significantly more.

May be able to create an advantage - takes a little work though.

Take a 410 brass case, trim it back so it's just a touch shorter than the cylinder. Use a 44 Magnum sizing die to swage down the part of the case that must make it past the 45 Colt chamber shoulder. You'll end up with a longer case, carry more birdshot or buck shot - no idea what powder or load to use, but whatever it is I guess it would carry more lead than a 45 Colt length case.

Might be an interesting project.

Might get there when fired out of a .410 shotgun, not a Judge and not when compared with full snort .44 Mags. Some factory .44 Mag ammo is on the tame side. Don
