Can you rechamber the 45 LC to handle 454 Cassull?

[jy951]

Is the bullet diameter the same on these two callibers?  Would it shoot accurately if it were rechambered to 454 cassull?  Has anyone done this?  what were the results?

It should work fine, the 460 S&W may even be doable, but no one has done one yet. The colt and casull used .452" bullets.

EDIT: This would only be doable with the 45Colt Carbine barrel and an SB2 rifle frame, not the 45/410 Survivor on the SB1 shotgun frame.

I forgot that I had emailed Wayne York on the Casull, one member was going to have a 308 Win barrel rechambered and rebored,  that was before the 45 Colt Carbine was available, here's his reply.

Hey Tim,

The guy hasn't contacted me yet, however, I see no pressure problems here.
60 KPSI is well within the range.  Your 270's and 25-06 generate similar
pressures and Handi's are chambered in those as well.  I would feel safer
with the big bore, in terms of pressure drop than I do the centerfire rifle
cartridges.  Although the Casull's initial pressure is high for a revolver
cartridge, it drops off fast because of the large bore capacity.

JY ... the only issue is chamber pressure.  Determine the max pressure for the H&R and then the pressure of the Casull reload you plan to use.
454 Casull's 300grs can be loaded in 45 Colt cases as one would normally load 452's ... with no reboring or reaming needed

I use the 300gr Casull's in a couple of 45 Colt lever rifles for long range matches.  But I don't run hundreds of them through the rifles

I think if I was going to do a rechamber of a 45 Colt barrel, I'd go for the .460 S&W, I could always load it down to Casull or 45Colt levels. Even tho the SAAMI MAP for the 460S&W is 65kpsi,  top loads are no higher than 57kpsi in Hodgdon's data, still well within the SB2 capabilities.

I know the Casull can handle .45LC, as a light practice round.  Been told the .460S&W can shoot the .454 Casulls, and the .45LC.  How about a rechamber so it could also accept .410 shells?  That would be a very versital gun.  .460, .454, .45, and .410, I could handle that.  It would make a great survival gun for the plane.  Especially with a survivor stock and a shorter barrel.  Capable of killing Grouse, Rabbits, Moose, or Bears.

Rog, I think that would be doable using a 45/410 Survivor barrel on an SB2 frame IF the barrel is 4140 which I think it is, but not sure, I'm sure the loooooong throat would temper pressures and velocity considerably tho. The big problem would be putting sights on it, not sure the barrel could handle the drilling and tapping AND the pressure. I guess you could epoxy/sweat sights on it tho.

ok, so the stock 45 lc will do fine with 300 gr casull loads?  i'm in IN and can use 454 casull and 45 lc for deer hunting, but not the 460.  i'm just looking at different options.  i'd really like to just stick with a 44 mag as ammo is cheap and it's fairly effective, but i don't like the issues i've read about the barrels.

Tim could or has it been tried to use 410 brass and load 452 bullets like a long colt i would think you would have to use a filler in the brass this would be in the 45/410 so the bullet would not have to jump so far to the rifling. just a question?

[moxgrove]

This has been done. If you search 450 Mongo you will see a fair amount. I have done it in the 45/410 but have not tried hot rodding it.Using over powder wads does work. you have to be careful about the air space so you don't ring the chamber. I didn't bother with wads when using fireformed 444marlin brass. worked pretty good with 2400 and unique. In the other thread about the 45/410 I stated that I have the set up now to roll crimp 410 plastic shells to an appropriate length. Some have had trouble chambering the longer brass in theirs with the 452 bullets in place. trimming and roll crimping, you could tailor your oal to the chamber. Again, I have not tried to turn it into a true powerhouse.about the air space issue I mean don't put an over powder card and then have empty space with the bullet then seated in the case mouth. This is the voice of experience.

[quickdtoo]

I don't think 45 Colt brass is made to handle Casull loads, that's another can of worms I think from what I've seen on other forums.
