Yes, there is always the question of what to do with the supplies you currently have. I understand that completely.

That is all I ever shot in my 454 Raging Bull. I used the Cast Performance 370 grain LWNGC with the dual crimp groove and a healthy dose of H-110. With the bullet seated in the rear crimp grove it would have almost as much case capacity as the 454. This bullet had to be seated in the front crimp groove in the 454 in order to fit in the chamber.

Interesting about FA. However, the SRH has inscribed on the cylinder and barrel both 454 and 45 colt calibers. I am only conjecturing here, but I would guess that the SRH cylinder is made of considerable stronger material that the FA cylinders. The FA 5-shots have substantially more metal between chambers, especially on the inside edges. The 6 shot cylidner of the SRH is amazingly thin (again, especially on this inside edges) yet can still, I suppose, handle the 454. Perhaps that is why they are willing to stamp 45 colt right along side 454...

Again, I am only conjecturing here. I think I'll give Ruger a call...

I shot some 45 colt handloads out of it today and obtained respectable accuracy, I think I'll try to work up a good load...

I shoot a lot of them in my 8" Raging Bull even though the manufacture said not to. All you have to do is clean the chamber before shooting 454's and it won't be any problem.

How does the accuracy compare between 45 colt ammo and 454 ammo? Thanks.

There is actually no reason to do this. ONe may safely load the .454 cases to lower velocity and power levels and not have the problems associated with shooting the 45 Colt ammo in a .454 chamber.

Except that I have dies, bullets, primers, and boatloads of cases for 45 colt already, but in general I agree...
