hey, I get it, the best tuned set up I have ever shot was a Mission Ballistic (OG 2013 model) set at 70#, 340 spine 31" Victory Hunters which should have been underspined even with the 100gr head; had crappy FOC, and probably came in at all of 435gr- fricking things shot like darts. I had to aim at different POI even out past 50 or I would break nocks. But having seen what happens on a hard bone hit, I decided to make a change.
