I'm really just curious. I understand the ability to shoot 38 Special out of a 357 Magnum because they headspace off the rim.
I was looking at http://www.brownells.com/handgun-pa...auto-460-rowland-conversion-kit-prod5003.aspx and started reading about this cartridge. Apparently, you can still shoot 45 ACP and 45 ACP +P once this conversion is installed. The 460 Rowland has a case length that's longer than the 45 auto to prevent it from being loaded in a gun with a 45 ACP chamber- this could meet with really bad results given that the Rowland's pressure is almost 3X that of the 45 Auto. What I can't figure out is how you can shoot 45 Auto in a pistol that's had this conversion since it's supposed to headspace off the case mouth. Being shorter than the 460 Rowland, how does it headspace? Couldn't the 45 ACP cartridge be seated so far in the chamber that the firing pin couldn't ignite the primer?
