I know without pictures of my form this will be hard to answer and Ill try to get some pics this afternoon or sometime this weekend. I am shooting 2-3" groups at 40 and baseball sized groups at 50. I have started shooting at 60 and 70 and arrows are relatively all over the place(shooting a glendel buck I can keep them all in the square but am missing with no rhyme or reason either way up or down. Would this just be a steadiness issue at that distance? It isn't like I am pulling or pushing everything they are scattered. I just didn't expect that much of a change. Any suggestions?
I know for me at any distance I have to remind myself of Mel Gibson in the patriot "aim small miss small" when I had a glen del I put a piece of tape on the vitals i think it was 2''X 2'' and tried to settle my pin as best I could on that spot, I wouldn't stack the arrows but i was happy with the group. I would try and focus on a smallish piece of the target see what that does for you! Good luck!
what are you shooting for arrows (size) and what's you draw weight? I know I have had issues with having incorrect spine weight and that caused inconsistency the farther out I got from 55 yards. just a thought, but hope you figure it out and get that grouping back at 60-70 yards! best of luck
How long have you been shooting at that distance? It could be something as simple as you're a little less comfortable and don't want to lose an arrow so you're doing weird stuff with your bow hand or punching the release. I shoot a big bag target for my long distance (60+ yards) stuff and it helps me be more at ease. There's a bigger margin for error so my nerves aren't up as high and I can focus on my form. For all my hunting range stuff (40 and less) I shoot broad heads at my Rhinhart block and deer targets.
Do you start at short distances, get "warmed up" and then go to longer? Try the opposite- start at longer distance. I find my tightest groups are my first few arrows per session no matter the distance. As you shoot little muscles get fatigued and you get wobbly. Form is harder to maintain. At short distances, no big deal. But at longer distance a little wobbly makes a huge difference. People lose confidence and start changing things- sight adjustments, overthinking things, and consciously or not start making tweaks to form or punching the trigger. I'm convinced most cases of target panic are initially caused by fatigue. Start shooting for precision and/or at distance cold. As you warm up, move closer for strength conditioning. Those little wobbles won't mess with your head b/c you won't be "off" much and the repetition will build the physical muscle without messing with you mental strength
