I have been reloading for quite some time. I have always produced loads that were in the lower 50% range relating to powder charges and have chosen mid grain bullet weights for any given caliber. Lower power loads have contributed to a long life of my armory. I have a need to push my 30.06 for the up-comming season. Published grain charges for 30.06 w/ 165 spitzer point, H414 are from 50 grains to 56.5 grains. I will be reloading the higher end of these charges - 54, 55 grains. My question, What are the signs of overpressure when loading high power for a non belted cartridge. I have read books on the matter, but think I may gain a better perspective of what to watch from the group. Thanks for your input.
