[QUOTE="highdrum, post: 2328271, member: 13732"] I usually run a paired charge ladder at 500y, I see the velocity nodes. I then charge in the upper half of the velocity nodes, and do a rough seating depth test in 005 incriments from 15-40k off lands. One or two of these will shine. I pick the one with best ES/group and load 30-40 rounds of this spec. I then tune at 500y. I have also tuned at 100y. You'll see the same results. The correct tune groups at 100y are usually 1 hole 3 shots. That translates into 1/3 moa at 500y. [/QUOTE]
