I shoot a few times a week but usually just field tips. Decided to sling a few broadheads this afternoon to make sure everything was still hitting right, before hunting in the morning. First shot w/ broadhead dead on. Field tip close as you can get without hitting first arrow. Did this a couple more times steppin back a few yards each time. All the sudden BH starts hitting about a foot to the right and 8-10" down. Thought it was fluke retrieve arrow shoot again. BH hits the same hole foot over, 8-10" down. Field tip still dead on. After several times same results. Switched BH to a different arrow. Arrow hits about 8-10" low but right on side to side. Only way I could get BH to hit bullseye was from 10 yards. Still scratching my head. Not hunting in the morning now. Sounds like im getting rained out anyway. Any thoughts?
