I shoot at a block target set at 30 yards. the issue im having is out of 3 arrows I will shoot 2 with in a 1/2 inch and 1 will be about 4 in. to the right. Even with 5 arrows i will shoot 4 with in 1 in and have 1, 4 or 5 in. off to the right. How can i get over this, it is starting to really piss me off.

and if i shoot 6 of them, 2 are off to the right
