How can this be? I am sighted in with 100gr broadheads but today i was going through some old gear of mine and found some 165gr simmons landsharks and decided to shoot one to see how it would fly. I must say it flew very well out of my set up. The thing that has me stumped is there is a 65 gr diffrence between what im currently shooting and the landsharks yet my 10,20 and 30 yard pins are dead on with the 165 grain heads as well? How can that be I would think that much extra weight would bring the point of impact down atleast a few inches if not more.
