...more on broadhead tuning
Well it been a week of frustration and research. After getting out on the lawn with a 10, 20 and 30 m target , with all my tools lined up i got started on tuning my broad-heads.
I shot 3 field tips at 10 then 3 broadheads to find a pull to the right by about 5 inches.
I decided to repeat at 20 and tune from there. this gave me about 6 inches off to the right. So i put the Omen max down and adjusted the arrow rest toward the field tips (left) by 2 mm.
repeated the shoots to find i had closed the gap by an inch at best. so once again out with the tools and moved the arrow rest further towards the location of the field tip (left)
again shots fired at 20m and the gap did not close! This is basically the theme that day for the rest of my dam day, as you could imagine i was getting pretty frustrated. So it was back to research and make a few calls to the always helps lads at Archery Direct.
An interesting and common issue come to light from my research - arrows hitting to the right can often be a weak spline arrow. But in this case that was very unlikely as i was running with 28in or 70.5cm (carbon to carbon measurement) 300 spline arrows.
So I thought it was time to get back to basics and do some paper tuning, this was a worthwhile effort.
here i found my nock end kicking out to the left - again this can be caused by weak spline. but i tried some shorter arrows with lighter tips which basically increases the spline, and i saw no change.
so i adjusted the arrow rest to the right to correct the paper tuning tear. no dice! this was starting to beat me down. The as coincidence would have it one of my regular clients and general "good bastard" email me a copy of an article from South Pacific Bow Hunter he was telling me about on our last hunt together. well bugger me this solved the issue. it was a Cam lean which needed a bow press and a bus cable to be twisted.
happy grouping
