71.0 3 shot @100 yds .25" group, AVG 3315 fps, ES 12, SD 5.

Ladder took me to heavier load than I expected and is compressed. Alliant data shows 69gr max for Speer 150gr @ 3304.
I have spent a lot of time and components trying to get an accurate load for this rifle, including 160 HH, 150 PH, 137 HH, most of which ran around .75" groups. I was lucky with this one - backed off 1 gr from max and shot a .25" group. Verified accuracy during sight-in. I will hunt elk with this next month.
