Hopefully someone can chime in with a solution to this. Occasionaly my arrow hits the sideplate and leaves a scuff mark on the arrow wrap. It is also a louder shot. I have experimented with many shafts and I am sure I have the correct spine. I am thinking it is my grip or bow arm position. It doesn't happen every shot, but I must be doing something to cause my arrow to hit the plate. I am shootng a great plains t/d 56 @ 28, 28" draw, three under, mfx 400's 29" long, 225/250 up front. This has to be a form problem but I don't know what to do. Thanks in advance..
