What do you think is wrong here?
I've got a question here about broadhead flight. Please bear with me, this post could be rather long.
This year is my fourth as a bowhunter. I get help from the local bow shop with technical aspects - they help me paper tune, they build my arrows and tune my broadheads. I'm not a tech wizard.
My problem is that my broadheads never fly to the same tight groups as my field points. I used NAP T-heads the first two years, Muzzy 100s the next, and this year I'm trying G5 B-52s. In all cases, my broadheads have hit well within 3 inches of my fieldpoint center, but each arrow/broadhead combo flies to its own unique spot.
This year, I have three arrows that impact 2 inches off at 3 o'clock, one impacts 2 1/2 inches off at 2 o'clock, another 3 inches off at 11 o'clock, and the sixth hits 4 inches off at 7 o'clock. What I have resorted to is choosing an arrow, and sighting in for THAT arrow. If it breaks in season, I nudge my sights to center for arrow #2, and so on. This situation is obviously not ideal. Again, this year's shoot was with 2-blade B-52s. Last year with Muzzy 3-blades the results were substantially similar.
I really make a big project out of this process. I shoot each broadhead 15 times at 20 yards, measure each shot to the quarter-inch, and record the shots on graph paper. I then determine the arrow's "center hit" by taking the median of the 15 shots.
I don't think tuning is my problem. I have paper tuned with field points each year, and shoot perfect holes. I'm getting no vane contact. Everything looks good.
My setup: Matthews MQ-32, 30 inch draw length, 55 lb. draw weight, ICS Beman Hunter arrows, 100 grain broadheads, total weight 438 grains. I shoot with a release.
