Number each arrow and shoot them all and mark where the hit the target.Repeat shooting a few times and see if it is the same arrow that is shooting good and that the athers might have something wrong with them.

I'll try it but i doubt that anything is wrong with them. I just bought a new set of Carbon Express Predators last week and have only shot each arrow during the paper tune.

I bet ya there is a few in there that something is wrong with them. I rarely find a whole dozen with consistent spine. I test on a spine tester and then, if I shoot thru paper, I can turn 120 degrees for three shots, and get three different tears.

I am still thinking grip or form as evidenced by the 1 in 4. Are you putting your weight on your back foot when you shoot? Do you have a wrist strap on the bow? Weight on your front foot will cause this. As will a weak bow arm.

By the way...how far left are the tears going? And what kind of rest is it again?

The tears are only 1/4 in. to the left. The rest is a Trophy Taker Drop Away, i believe it's the Shaky Hunter.

Heres a photo.

Thats a large stabilizer, Does the bow fall forward when shot?

I would say that it falls slightly but nothing out of control.

If a bow is not balanced, paper tuning can be tricky, because you are trying to catch the bow after the shot.

IMO,the left tear on those bows would be from a weak arrow.Those bows shoot HARD and arrow charts do not work for them.You need to go stiffer than the charts.

Drop aways really make this tough for they drop to soon to guide the arrow straight if the spine is borderline.Spine needs to be near perfect for perfect bulletholes with a dropaway that drops early.
