I run most of my Hammer bullets in the area of .100" off the rifling. I seat the bullets to maximize the amount of bearing surface in the neck and most loads just end up around .100", but there are exceptions. Recently, I started fooling around with the 85H bullet in my Creedmoor. That bullet is so short that I'm at .213" off the rifling. With a good load of Varget and in a 26" barrel, I was able to get 3,700 fps without much difficulty.
