Jam and touching are two different things. EC's method of finding jam is loading a dummy round with light neck tention ( .001-.0015 ) and moving the bullet out until it sticks in the lands. My guess would be he is about .035" into the lands or past touch. I load the 90gr Bergers .004" into the lands 29.8gr of LVR with no pressure signs and get 2840fps out of a 22" barrel. I do this because it groups best and less of a chance for the bullet to jump from the bolt slamming closed.
