RE: 3D targets suck!
Carpmaster>>>-------->First, I am assuming you are shooting carbon arrows. You say you are using epxoy. Okay, make sure you are using the 24hr cure type. Fast curing epoxy does not work that well.
NOW, I too shoot carbon arrows, and have in the past used the 24hr epoxy, which is supposed to be the best, BUT both my wife and I were losing points. What we did was to switch over to Easton "low melt" , and we haven't had any problems since.
Give it a try---hope this helps.
