.454 casull/ruger super redhawk alaskan question

[Hawgman]

From what I understand you can fire .45 long colt in a .454 casull ruger SR alaskan. Anybody know if you can shoot .45 auto rim through it safely?

Interesting question.

For one thing, isn't 45colt/454 casull sized .454 where .45acp/autorim is .452?

I might be wrong but aren't the newer guns in 45 Colt sized 452 ? I don't have one but have heard something like this.

Actually the 454 casul is just the cartridge name. It uses a .452 diameter bullet.

To answer the OPs question; as long as you are using a moon clip to hold the cartridges, you should be fine. If you attempt to load the revolver without the clip, the cartridges will go all the way in the cylinder and the will not fire.

If I remember correctly 45 colt barrells prior to WW2 had a groove diameter of .454 and those after are .451-.452.

The 45 auto rim's cartridge rim is .030 to .040 thicker than the 45 colt or 454casull 's rim. If you managed to close the cylinder (which I doubt) it would probally bind trying to rotate. There are also some case difference's that I think would play havoc with chamber pressures and such.

The short answer would be: I wouldn't shoot 45 auto rim in anything but a revolver designed for 45acp with moon clips or 45 auto rim.

You know, as soon as I read your post a memory about .45 auto rim's rim being oddly thick came to mind. I remember that now from folks sometimes wondering about the auto rim in a single action .45LC. Thanks Chas, you da man. A buddy of mine does shoot .45 schofeild(sp) in a DA taurus .45LC revolver. Says it's a real efficient use of powder. Thanks all for your replies. OSA's great!!

****, I guess I misread and jump the gun. Mistaken it for the 45 ACP.

I have a ruger .454 and there isnt enough room for the half moon clips you would have to use .

Pinnacle will machine the cylinder in these to allow one to use .45 ACP with moonclips, so I imagine that the auto rim should work without issue or modification.

Chas, thanks. Good to know I wasn't going crazy.

.45 colt (old) = .454

.45 colt (modern) = .452

I'll try to remember that.
