As you may or may not know the above cartridge has only been around 20 years and there is still only one brass manufacturer that I am aware of that makes the casing (Starline Brass). Additionally, the complete cartridges are only sold by a few vendors. I would like to know (if for some reason this brass became unavailable) if anyone knows what other brass casing could be used to manufacture this round. It is exactly like the .45 ACP but is 1/16" longer and is stated to have more support in the webbing. It uses .45 ACP dies for reloading. Any help from any of you folks who have looked into this will greatly be appreciated!
