[QUOTE="BrentM, post: 909032, member: 61747"] Good info, as usual. I tend to start around .020 to .050 to find max charge. Then back it off and shoot depth. I reload in the field so I don't waste ammo. Seems to work ok for me. I have 2 rifles that really like .100 off the lands. This is base off of shooting the highest velocity I can safely get away with and then tune for accuracy. Be cautious, though, seating close or in the lands with a max charge weight at say .050 off. You might have a problem as seating close can and usually does produce high pressure. I chronoed loads with the same charge weight over 6 depths and noticed pressure signs and velocity changes on several calibers. Based on this I too believe a rifle and bullet have have a sweet spot in regard to seating depth. [/QUOTE]
