I just began shooting 50 yards this weekend trying to tame that distance. It's not bad. With my old bow (finger shooting) I was glad to hit the 4X4 and not wreck an arrow.
Sorry, I didn't take any picture, but as awful as my first group was, the last one one wasn't that bad. I had 3 of the 7 arrows with 4" while the rest were scattered bit. I have to be more diligent with my "list" : thumb to earlobe, elbow high, relax grip (X2) trigger.
From you guys who regularly shoot at longer distance, is there a feel to it too? Because really, 1 mm off and the error is multiplied several time by the time it hits the target. The reason I'm talking about a feel, is because I think my sighting of the target is never perfect at that distance.
