I learned to shoot on recurves and long bows. I shot a compound bow for years because it was easier to shoot and required less practice and, with work and everything that went with it, I could still hunt and harvest game. Now I'm back to recurves and long bows. All have been bare bow, off the shelf, shooting fingers, even the compound.
My groups and accuracy have been erratic. Finally, in frustration, I told myself to quit thinking and just shoot. I started hitting. The difference? I shoot three under and have always anchored with my index finger at the corner of my mouth. I noticed that when I just shot, my anchor was past my mouth by almost an inch. I came back four hours later and used the new anchor point. Succes.
I have no idea why what worked well for so many years (I started shooting as a child) changed. Maybe it's the bow, maybe it's me. My new draw length is now close to 29.5".
Anyone ever had to adjust like this?
