I am trying to seat the bullet at the correct depth for MY gun, a Rock Island Armory Tactical Model 1911 in 45 ACP.
I am currently loading Berry's 185 grain round nose bullet above a charge of 4.7 grains of Clay's with a OAL of 1.2-1.22". I'm reasonably happy with that load. However, in the spirit of constant improvement that is inherent to handloading, I'd like to see if I can make it better.
I did some internet reseach and read that if you seat the bullet such that the rim of the case is level with the hood on the barrel, you are seating THAT bullet at the correct/optimum depth for THAT gun. So I tried this. It turns out that even with the bullet ridiculously long (1.3"), the bullet still isn't level with the hood. So then I tried an empty, sized case, and the case fits at the same spot.
Is this what they refer to has "headspacing on the case mouth"? If all this is correct, perhaps the method that I read about with regard to the barrel hood is incorrect?
What are others doing to get the bullet seating optimal, besides trial and error loading?
Thanks in advance, Chris
