Chambering a .45C/.410 barrel to .454 Casull

[Couger]

Has anyone ever done this?

Get a .45Colt/.410 shotgun barrel fitted to an SB-2 receiver and have it re-chambered to shoot the Casull cartridge?

The barrel in question is 20 inches long, fully rifled except for about 2-2 1/2 inches near the muzzle where a choke for the .410 screws in.  The "choke" actually helps stop the spinning .410 shot-load so it will pattern without spinning all to heck.

Anyway, it seems there should be enough steel to support the working pressure of the .454 Casull, unless the steel is actually too soft?

Anyone have any experience when the Casull in a Handi-Rifle?  Or this [project] idea?

Perhaps the key to this project is the type of steel used in the .45Colt/.410 barrel, which is actually sold on a SB-1 frame ......

Thanks in advance.

Have you tried to put a 454 shell in the chamber yet ? They fit fine in mine make sure you use a SB2 frame though. Kurt

Hey Kurt,  thanks for the reply.

I don't have a .45C/.410 barrel at present.  Have you actually shot shot Casull ammo in yours?

My first ever yours experience was an SB2 .45C/.410 Survivor I bought from a private seller at a gun show.  Only tried .410 loads in it before selling it again after disappointing findings with #6 shot.  Should have tried #7 1/2's.

If the steel in such a .45C/.410 barrel is hard enough, I think the idea would work - from some of the postings I've read from other Handi-Rifle loons.  What I specifically remember about the .454 Casull on an SB2 frame is that it should work, but that a .460 might not.


Anyway ..... further comments?  Thanks!

I only had 2 Casull bullets and shot them both. Kurt
