I finally got some range time to work with Alliant Power Pro 2000MR in my 10PC .308 today. After working up in .3 gr increments with the bullets touching the lands I found an accuracy node at 46gr (middle of the road load) using Lapua brass, Win Primers and 165gr Sierra Game King HPBTs that gave me a 5 shot one ragged hole that looked like 3 overlapping, a clover leaf at 100 yards. I'm wanting to try a couple of other bullets I have on hand in the same weight. (Accubonds, Ballistic tips, A max, Interlocks) Would it be effective to just stick with the 46gr charge weight and change bullets and see what happens or will I need to start over and do incremental charges with each bullet?
