I am shooting FMJ 300's at 29" with a 100G tip. So far results are amazing. Just got my insanity sighted in today to 70 still have to finish from 80 out. I should be able to make it to about 140 with the slider portion I am hoping. I shot it over chrono and it is at 303 fps witch is putting 102 Lbs of KE should have my penetration issues taken care of.
