Arrow point of contact?

[smbassman]

Here is the situation; My bow is paper tuned and punches perfect holes, my groups are very tight(typically close enough to close thumb and forefinger around three arrows at 30yds). Using one pin at 15yds I am centered 2"s high and 2"s right, same pin at 22yds I am dead center up/down, left/right. Same pin at 30yds, I am 3"s low and 2"s left. So why the left/right shift? I thought I might be canting my bow but a bubble level proved otherwise.

Details - Parker single cam (65#s, 29"), release w/ string loop, bodoodle rest, carbon express arrows.

Thanks!

Try using a 125 grain head. You're results are consistent with a stiff spined arrow.

You could also move your lbs up to 70, that would probably correct it as well.

Bullet holes in paper really mean squat, they just look pretty.

Looks like you beat me to it Doc!!

:yeahthat:

yep has to do with the amount of flex when you shoot and all that archers paradox stuff, change arrows,or heads,, or allow some kentucky windage.

If your spine wasn't correct you wouldn't be able to paper tune perfectly. I think you should shoot from paper at point blank, 6 feet, and 10 yards to see if you have a perfect whole at all distances. My guess is you will not, and may need to move your rest out just a touch. Do your field tips and broad heads follow the same pattern for you? If not, it could just be speed and wind planing. <----<<<

Agreed...you are too stiff.

Adjust components to get a 12-15% FOC.

If you want to see the manifestation of the condition in practice, throw a lighted nock on an arrow and shoot it at dusk. You'll clearly see the path of the arrow which will explain your interesting point of impact.
