I just got my bow setup after having new limbs and cams put on it. Anyhow my field tips are flying great even out to 60 yards. Well, today I decided I was going to go hunt some woodchucks with my bow. I had some old Spitfires laying around I that I was gonna try and I figured just for the heck of it I would shoot one just to see how they flew and save the other two for hunting. Anyhow my arrows keeps flying erratic and way left which I think is weird because I know mechanical are supposed to shoot like field tips. Im really stumped my Judo points fly a little better but not much. Then I shoot my field tip arrows and they look great again. What gives?
