OK,
I got my 125gn ace BHs in so I'm gonna try and tune them. As I stated before, my draw length is 26". The shafts are 11/32 POC 40-45# spine. I cut them down to 28" and installed nocks and fletching (sealed and straightened of course). I have only glued on one BH. I figured if you guyz help wth this one I can do the rest. If I can't get this tuning thing down I'm not going to hunt with this bow cause I don't want to risk wounding something do to poor arrow tuning. so here goes.

I aimed at the center dot from 15yds with no adjustment to distance. 40/50 shots landed around the lower left dot as pictured. I think I have the nock hight ajusted where I want it but have read conflicting articles in the internet about where to go from here.

Shoot some fletched with field points also to make sure you can see what the BH arrow is doing compared to a field point arrow. Otherwise you could be thinking you are aiming in the middle, but it is your aim that is off and not your BH arrow. I shot the BH first and then the FP arrows so I don't damage arrows.
Are you right or left handed?

r handed

WHump Sez; Befor we go any farther---what poundage is your bow? Hunt Safe.

Are you wanting a 27 or 28" arrow. It looks like you are shooting to stiff an arrow. I have always thought the measurement is from inside nock to back of point. Thats not what I see in your photos. windwalker

Assuming your shooting your fletched filed points to center of that target then your arrow is too stiff and your nock is to high or to low and your arrow is bouncing off your shelf and shooting low. If your not shooting field point arrows, start doing that as part of your broadhead tuning.
Knowing your bow type, center cut, and weight at your draw length will help. Some pic's of your form would be good to see if you have the correct draw length. Bad form weighs heavy on all other factors.

Your arrow is cut to 27" not 28".It probably won't affect your impact but I believe you have left wing feathers are fletched right helical.

JimB is correct.
