Everything between 57gr to 58gr was .75"-.9" groups at 100yd. If I remember correctly I was 2850fps to 2900fps. Work got busy but haven't got out again. Tried few seating depths though. .075" to .050" was tight groups. .025" opened up, and .100" opened up. Got some loaded in larger batch at the 57gr to test more velocities and SD as well seating depth.
Heard lots of issues getting ablr to shoot. I've found they need to be jumped decent amount. I like doing larger jumps at first testing seating depth. I hunt with these so started at .025" then .050 .075 .100 back to saami coal which is 2.950 I think? My Sako S20 I can load right to jam an still fit in magazine with room.
I got lots of berger 156gr eol to try this spring as well.
