What is the difference between 455 dominion and 455 Super Mag?

[surfer365]

Does anyone know the specs on the 455 super mag? I'm looking for new brass that is the same or similar to 455 dominion.
Thanks

Nevermind my dislexia is working overtime to night. I was looking at the 445 super mag, so that will not work.

.455 Webley can be made from .45 Colt cases shortened and the rim thinned.......Harold

Or just buy them from Fiocchi or Hornady. - dan

.45 Auto Rim with the rims thinned: perfect substitute for the original .455 Colt cases made by Dominion, which actually was a Canadian copy of an American cartridge that duplicated the original British .476 Enfield dimensions.

Are we all confused yet?

But that's the stuff.
