My test loads are 168gr nosler custom competion bullets
varget powder
BR-2 primers
Lapua brass
nearly every load was looking promising
Its been awhile since i've had time to play around, without my notes in front of me I don't remember my start grains with powder, but I too was 5 or 6 thou off for bullet seating. I'm definetly no pro with precision shooting by any stretch of the imagination but these rifles seem to like almost anything with a heavier bullet. just my thoughts
