Berger 210vld touching, jamm or jump?
Worked up a pretty nice load with my 300WM using these bullets, H1000, Fed215M, a new Kreiger 1-10 twist at 27 1/2" on a Win mod 70 action, mpi stock, pillered bedding, Wonder Optics scope. First thing I noticed was the velociies were considerably higher than the load data. Over 2900 with the starting load. No pressure signs throughout. Settled on 75.8/76.0/76.2 all clumped under a minute. Got 76.0 and 76.2 at .6 and .7moa 3 shot groups at 300yds. Now all testing was with the bullets just touching the lands as Berger suggests. Velocity for these loads was avg. 2982fps. Definatly up there but as I say no pressure signs, miked the web, no sticky bolt lift, no extractor marks very slight primer flattening. Has anyone found an improvement with these bullets by jamming or jumping them?
