What would the bullet weight be and what velocity could the .454 get out of a rifle?
454casull rifle??

Well, if it's going to be in semi automatic form, we're talking a whole new beast and such a beast already exist, but in 50 AE. Some outfit makes an AR upper (carbine) in the cartridge. Fifty cases are also better suited for feeding in a semi and have hairsplitting better ballistics. I believe the gun is called a Hammerhead, Sledgehammer or Hammersomething. Or some corny catchy name.
George,
A 300 grain bullet powered by 30 grains of H110 will produce 53700 CUP and 1716 FPS from a 9.375" FA barrel. Would guess that double the barrel length would add another 300-500 FPS. That velocity would almost rival 45-70 for supremacy.

I had to come back and mention that I did think of a bolt action that *might" serve as a base for such a rifle - at least the action is short enough to make sense.
I'm talking about the Spanish Destroyer Carbine which was chambered for (I think), 9mm Largo.
This is the only bolt rifle I'm aware of that was ever chambered for a pistol cartridge.
If the .454 would fit in that envelope and the rifle can handle those pressures... it might serve as a base for such a conversion.
I think cutting down any other action to fit a pistol cartridge would go well into the 10k range before you were finished.

NO! NO, NO, NO! (Unless this is a present for Janet "I take full responsibility" Reno!)
The "Destroyer" is not a very strong piece. I would be reluctant to rebarrel for 9x25 Dillon, much less something that could very well wreck a Moisin-Nagant.

Well, if you say so. I wasn't sure about the Destroyer, I've never even seen one.
I don't know of any other bolt rifles that would be suitable for a pistol cartridge.

CZ has an excellent reputation. Sounds like a plan, to me - keep us informed!

Yes please! Though I think it's a bit light for our bears here on the island, we could go over to the mainland and whack a moose, or down southeast and pile up some black bears.
A suggestion - or an idea - is to look at lengthening the chamber beyond the normal parameters so you can shoot heavier bullets up to the 500 grain range.
I don't think the additional free-bore would hurt accuracy (doesn't seem to matter in revolvers) and you might want that extra weight to shoot really big stuff.
I'm no gunsmith, so that may be a bad idea for reasons unknown to me, but I would certainly look at it. With heavier bullets, I think such a rifle would be adequate for anything in North America and most stuff in Africa.

850 fps? I'd think you could do better than that with the longer barrel and slower powders that a rifle would give you. Have you checked Thompson Contender loads for .454?
