I set my seating die for a commercial cast ersatz "#68" cast SWC to headspace on the bullet shoulder in a Wilson barrel, as shown in the color diagram regularly reposted here. It was 1.245" OAL and I did not find it necessary to change for other guns. But I don't have a Ruger.
Ok thanks. The SR1911 is my first .45 so I am in that "dont know what you dont know period" still regarding whats normal and whats not. Thanks for the clarification. The more info the better.
