took a little time today and set up a simple primer test to see what the difference would show on paper. Took a given blue dot load 12.0 grains with trimmed brass ,55 grain sierra bullets and sized with a Lee collet die. Neck tension is consistant ,as i took an old torque wrench and converted it for my handle on my press. All i varied were the primers.CCI 400, CCI 450 and Federal match primers.. Here is the results..100 yard target 1" squares.Posted Image
