Thanks for all the info guys. I got the bow back in the spring and have been practicing at 20 yards for a few months. Like i said, i feel confident at 20, but yesterday was the 1st time i practiced at 30 yards. yesterday i was doing ok, today, blah. I just could not believe the difference from 1 day to the next.
I also notice at 30 yards i hold the bow on the target longer before releasing. I also notice the longer 1 aim at the target the more my bow starts to move.
I also read up on torgueing the bow after someone mentioned it, this could be a possibility. Any suggestions on this?
