[QUOTE="memtb, post: 1541062, member: 75451"] As mentioned above....most manuals are “very” conservative compared to the ‘60’s/‘70’s! But as you stated, there will be differences in barrels....some faster, some slower. Unless you own a “strain-gauge”, about all you can do is slowly work up your charge, constantly monitoring pressure indications. Often you will get a fairly steady increase in velocities with the increase of charges. If you step-up the powder, and do not see a velocity increase, this “may” indicate you’ve reached maximum! For what is worth, I do my load development on hot days....making sure that I am within safe pressures on hot days. Though many of our modern powders are fairly temperature stable....I err on the side of caution! memtb [/QUOTE]
