    I have a zxt 60# bow I am shooting gold tip pro hunter 55/70 arrows w/100 grain tips. I can get a perfect tear w my 2″ blazers but when I try the bare shaft test I get a 4″ tear to the left. any ideas on why it is doing this?

    I have a few thoughts:
    First, when you say you get a perfect tear with fletched shafts, is that at two distances minimum? … 5′ and 10′? It is possible to get a bullet hole at one distance, but not after moving back a bit. If this is the case, the bare shaft will show it up.

    Second, bare shafts are finicky. They will show up lateral string travel (idler lean, cam lean, bow hand torque, string contact with face, etc.) much more than fletched shafts.

    Finally, bare shafts are finicky about spine orientation. Rotate the nock on the bare shaft to see if the tear changes … find the sweet spot for the nock.

    I have a question about this.  It may seem alittle picky but when you shoot at 5 and 10 feet, it that where you place your feet or should the front of the bow be at those distances?  if you stand at 5 feet the the arrow is approximately only 3.5 ft from the target.  would this make a difference?

    Thanks.

    Distance is from where the feet straddle the line. A precise starting distance is not important, just that it is somewhere 4′ to 6′ from the paper as Easton Arrow Tuning and Maintenance Guide recommends. Once a good tear is achieved at 4′ to 6′ distance, then move back 6′ from the first position, a precise 6′ is not important either. The object of the test is to get at least two visual indications of the arrow flight. Some paper tear procedures recommend three distances … about 5′, 10′, and 15′ or 4′, 8′, and 12′. They all work equally well if the procedure is followed.
