Re: Bullet into lands= velocity deviation?
I am using all Winchester brass fired from my rifle, am very particular about measured amount of powder and Remmington 9 1/2 primers. Not doing anything special just resize, trim, deburr, clean primer hole, reprime, measure and add powder and seat 115gr Berger bullet. I am extremely new to reloading but, can't figure out what I must be doing wrong. Measurments are from a Competition Electronics Prochrono Chronograph. Have gone to the range several diffrent days and used several diffrent loads but always with the same problem. Any ideas? Thank's, Brad
