View Full Version : .454 Casull Rifle Receivers

At some point in the future- after my current project gun is done- I would like to have a 16.5" bl .454 Casull/.45 Colt rifle built. I believe there are two ways to do it, but I am unsure of back thrust of the .454 relative to rifle rounds. I do know that its pressure is much higher than most rounds.

I believe there are two ways one could go:

1. Bolt action. Again, I don't know what type of action will be strong enough. (Arisaka? Mauser?) I would really like a repeater, but the only .454 rifle I am aware of as of this point is the Browning High-Wall...a single shot. If a bolt-actioned receiver capable of handling the force is too hard to find, then

2. Double rifle. I believe it should be possible to have barrels built that would replace the barrels on one of the inexpensive former Com-bloc double-bl shotguns we're seeing now. (I would go for an over/under if going this route.) I would prefer more than two shots, but the advantage of this method would be that I could also have barrels made in 9.3x64mm, .45-70, .450 NE, etc.

Suggestions? Will it be difficult to find a (hopefully value-priced) bolt-gun receiver that will handle the fire-breathing .454 loads? If so, will the double 12 receiver do the job? Thanks in advance!

Siamese Mauser..they have been used with 45-70 extra hot loads.
Winchester 95, big nuff and stout nuff. Box magazine.
Marlin 1895, big nuff and stout nuff. Tube magazine.

Happy pondering....Sam

How about a US Enfield action or a P-14 Enfield...the receivers are MASSIVE...

Just thinking out loud...

What's the nominal pressure on the 454 casull?

I would imagine if a modern bolt action rifle can handle bottle neck rifle rounds at 65,000 psi, it should handle the casull. Unless that round is a pressure monster and I just don't know it.

I would also think that if a Marlin 1895 can handle 45-70 cor-bon loadings it could handle a casull. Certainly the lever action platform lends itself to rimmed pistol rounds maybe better than a bolt action.

I'd put my trust in a strong single shot falling block action before a codgered together double rifle outta an original shotgun action.

My thoughts,

Spectre, I'm not sure what the max pressure is for the .454 but some of the standard loads for this round generate 52,000 CUP which while are monster pistol loads would be fairly easily digested by 98 Mausers, Enfields, Arisakas etc. A Siamese Mauser might be the easiest conversion and I'd have to look into it but a Mosin Nagant might also work well.

The 454 operates at relly high pressures. Winchester had to get new equipment to test the proof loads. The Marlin 1895 is rated to about 40,000 lbs. I would think the 7600 pump rifle could be used.

Is Siamese Mauser suggested because of the force this cartridge generates, or because it would easier to modify the bolt face? I don't think of the .454 (a slightly stretched .45 Colt) as an enormous round (less than 1.796"), just a powerful one- on the order of a .45-70 at the receiving end, but from a pistol round.

George, I would consider the Nagant- if one could find a way to have a real, useable safety on one!

Hodson lists reload data at up to 53,700 CUP.

Spectre, yes the Siamese uses a rimmed cartridge to begin with so the conversion would be a little easier on it. I researched the Nagant a little yesterday and the highest pressure I found it proofed with so far is 49,000. That was in Frank de Haas "Bolt Action Rifles". He also said that several had been converted to 30-06 and had blown up but he seemed to be of the opinion that these were simply chambered without setting back the barrel and that the blowups were due to oversize chambers. I can't imagine a 30-06 blowing one if it was chambered correctly. I'm still looking into it. George

George, I know the Nagants are very economical, but is there a practical way to put a useable safety on them?

Spectre, I'll have to look one over and give it some thought. There aren't any aftermarket safeties that I know of for these rifles but maybe I can come up with something. I can't promise. I'll have to put my inginear cap on. George

What does CUP stand for?

What about buying a Marlin .450M and using it?

CUP = Copper Units of Pressure (I guess!)

BEWARE the Marlins! They are at their limit at 40,000 while the new weaker 454 Casull ammo runs 52.000. The older Freedom Arms ammo ran to 60,000 and many handloaders pump them up to 80,000

CZ is apparently using the same frame on their o/o shotgun as their new .458 Mag double...I just hadn't considered the problem with regulation.

I just can't see (at this point in my life) paying $800 or more for a single-shot rifle that might never be fired at targets more than 200 yards away.

I'm certain it is a beautiful and responsive arm; were I to get a high-wall, though, I believe 'twould be a .45-100, or somesuch.
