Hi James!

Thanks for the inside info.

Have you made any .455 cases from .45 Colt? Besides shortening, did/do you have to do anything else? I have been thinking of making some from .45 Colt or .45 Schoefield cases.

My 1917 Mk VI has been shaved, but just barely. It works fine with acp brass and S&W half moon clips. .45 Auto Rim brass will not work (I tried it), the rims are too thick. Full moon clips I have tried are too thick.

I did get a box of Hornady .455, and fired 6. or rather, 5. One didn't fire, and a couple of the others pierced primers. So, essentially, my gun is cut just enough so .455 won't work right, but not enough to take AR brass or a thicker than S&W 1/2 moon clip. .45 Colt/schoefield rims are just a little thicker than the .455, so I'm thinking that may make enough of a difference for the brass to work. Loads, of course would be kept to Webley appropriate levels.

Thoughts on this?
