If I may, I wonder if any of you could give an opinion about the velocities I'm getting with it. My handloads all seem to be slower than what the limited load data indicates I should be getting. Top powder charges clock under 2100 fps with 160 gr RN and about 2150 fps +/- with 140 gr spire points. These velocities will certainly work on game and they are quite accurate in my rifle, but don't approach expected speeds.
