Okay so I'm tuning my bow, discover the nock point is about 1+ inches off, fix that. Now when I shoot field points they hit good from 10 - 30 yards, in pretty much a straight line right where they should. They have a 400 spine and are 29" long. Put on broadheads and it looks like I'm shooting with my eyes closed. they are all over the place, no pattern. I try shooting broadheads and they are all over the place... okay switch arrows to Beman ICS Hunter 340. Field points are hitting fine switch to Broadheads Now i have one Beman ICS Hunter 340 that will hit the X or in line with the X from 10 to 25 (didn't bother shooting 30). 2 other Beman ICS Hunter 340's are all over the place. Same Muzzy 100 grain heads and exact same arrow setup. these are brand new just took them out of the pack heads, doesn't matter which head I put on which arrow. WTF is going on?
