I believe this is a form release issue. Here's what's happening.
Specs 60" 51#@28" buffalo bow with SBD 8 strand padded loop string shot with glove off the shelf padded with Velcro.
Arrows 29 1/8" long 2018 Easton gamegetter with 4" parabolic RT helical feather factory insert and 145gr point.
I just got my new to me bow ( Big Jims Buffalo). In anticipation to getting this bow I built a paper tuner. So I loaded in an arrow and first one through bore a bullet hole, Great. So another and it tore point left fleth right 3" tear The next few shots were the same except One was torn 5"
So as I read it that's stiff spine so I up it to 175gr point.
I get one bullet hole and then tears as above with point left fletch right.
So I try 200gr get one bullet and tears as above. So on to 225gr same thing 245gr and the tear is down to an 1". I focus on feeling a good release and bang, point right fletch left. ( weak)
I keep thinking how I got a bullet hole here and there.
I have really been trying to refine my form but I've only started shooting again a few months ago after decades off and I start thinking more about this being a form issue.
So I go back and discover when my release feels real nice I get a bullet hole with the 175gr heads. 4 out of the last 5 shots.
Now this makes me a bit confused. I was expecting to tune the arrows to the bow and thought that this would be something I might have to get within 5-10gr point weight and exact corect shaft length, yet just the slightest lapse in shooting means I need an extra 70+gr upfront to offset the reduced performance from a slight off form/release?
Now it feels like if it's not feeling right bang I get a tear point left fletch right. (dynamic spine stiff).
Is that normal? I don't feel like I'm overdrawing or anything when I get a bullet hole with the 175gr points.
Btw I'm standing both 6 and 8' from the paper with the same results. Hi/lo seems spot on. Did I mention my heads spinning?
Cheers
