man, i was just going to post the same problem. sometimes my group is tight enough that i hear the arrow hiiting another in the target. then it all goes to s#!t. i dont think mine problem is the bow i sure it is me. arrow flight looks great. and i've done the walk back test out to 30 yards. i also have aproblem with my left shoulder and neck muscles from an old work injury so i have to limit my shooting to about 15 rounds of 3 arrows
