Its not the center of the heart
HM this is ideal grouping for any hunter, If it were me, I wouldn't make further adjusments,adding the 40 yd group. Had to make a scope adjustment for this group. The scope was really close for each graduation, sight in at 20 yds set the bolt fps and each group after that was close at the 30-40 yds. Bolts are Easton's full metal jackets.
