It was loaded at 1.175. 1.156 I have not loaded just did plunk test to figure out where it needed to be for that barrel (sr1911). My other barrel ( colt 1911) plunk tested at 1.173 for the same bullet.
My book says minimum oal is 1.155.
Can this be caused from an oal that should have been shorter. This was 1.175, later test showed the barrel to require 1.156 (manual calls for minimum oal of 1.155).
