Well after a 2nd day at the range I have my hunting load figured out. Set my target at 20 yds even, and began with 80 grains 2f., and a 350 grain maxi-hunter. Shots were again consistanly low. Went to round balls, and .248 powerbelts all about 3" low. Upped the powder charge and tightened the grouping but still low. I then moved the rear sight and the maxi-hunters stayed low, round balls were about 2" low, and the powerbelts hit about 1" high. Moved the target back to 50 yds and was able to stack the powerbelts 1/2" high of the bull at that range, and at 75 I was about dead on. So I will be sticking with the .248 grain aero tip powerbelt with 90 grains of 2F goex.
