Is there a big difference between large rifle primers? I just ordered a kit to change my Savagd 10ML from 209 to LRP so who makes them and who makes the best for the powders I burn, R7, H322, IMR 4198, AA2015, IMR 3031, VV 133. The only thing I know is I will get better combustion an. More consistency. And that I will probably need to rework my loads some. Is there a source maybe a manual that will help fill in the gaps.
