Took my TC firestorm .50 to the range today. All shots were fired from 25 yds, and all consistantly about 1" low and 5" to the left. I was shooting 90 grains on 2F goex, and tried .350 maxi-hunter, .490 round with pre-lubed .015 patch, and .245 grain powerbelt. I attempted to move the sights up, and to the right but the shots would move no closer to the bull. Do I change powder increments, diff patches, or some other kind of sabot?
