150 grains of pellets is not needed. 270 grain powerbelt is a great starting point, but i really would use loose powder and stick with around 90 grains. I only use 80 grains loose T7 and am only 4" low @ 150 yards. I sight dead on at 100 yards.
I'll make a thread with detailed info and pictures of the last deer i shot. I'll get that up once i finish lunch
Good job with those deer you shot, have any pictures of the 11 pointer?
