| I re-iterate the 520's with 100 grain points will be tuning 38-40lbs so just forget it and shoot.
Sam you are so under spined that if you think they tune you are torquing the bow, 450 x10 at your draw length for 46lbs, 410 for 50lbs and some top archers have gone for sub- 400 spine on 50lbs at 29.5 inch arrows
