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.Mine is a cz527 bolt action and 99% of the time I just have 1 round in it so I don't have to worry about movement in the mag. I am getting a custom 3 round mag made but not sure I will have to worry even then.
I like the way his is concrete , jam it in pull out and back off some, so the question would be back off how much . I think Eric starts at .020 off (I would ave to go back and look ) and works back from there How does what you do differ from that
How do you find Lands ?
Thanks
