[QUOTE="highdrum, post: 1815531, member: 13732"] I will say, adjusting seating depth incrementally by 3 thousandths is the way to go. Larger spacing can let you skip right over where the accuracy is. I suggest starting 14-15 thou off, and basically load 3 rounds in 0.003" incriments till you get to 45-50 thou off the lands. I guarantee you'll find a place where it likes to be. Attached is an image of one my seating tests. I had 2 more groups to shoot that we further off but didn't, as I found where the bullet liked to be. Now that I found seating depth, I will load 3 rounds 1.5, 1, 0.5 gr below, ans 0.5, 1, 1.5gr above and see where it's the tightest grouping. Serval of these groups were 1/2 moa or less @ 200y. 338 rum, N570, 300 bergers @ 2890fps. [/QUOTE]
