A while back I started playing with the .308 brass. The Rowland stopped my experiment. I ahve had it to the limit with no set back. My thinking is since the rearward inertia is disapated before it has time to move the gun it also wards off inertia pulling or pushing the bullet in the case.

In the Glock I worked with seating lengths till I felt I had perfected it with each bullet. The way the bullets feed in the Glock vs the 1911 may be beneficial in allowing the bullets to chamber with the lengths I came up with without damaging the bullets.

Here are the seating lengths with some of the bullets.
