Russel! I have it set-up now but noticed a little vibration coming from it ,so I put a little mole skin undernieth the metal plate that run's along the shel,f it seem's a little better now but I was shooting at 20yrds and had a flyer rip into my shed and broke the arrow haha. Are you saying to leave the shelf off ??????and just go with the arm?????
Got to go pick the kid's up from school; it's raining here now but I went to the range this morning it was absolutely georgeous out. I am shooting well up to 30yrds but grouping is a little loose at 40yrds .I figure I was getting a little tired of shooting that might be the problem ,needless to say I really haven't been shooting since the end of January so I might be a little rusty.
