I shoot a hoyt maxxis31 65# 27in arrow. I'm trying easton axis st 400's 2in vane and 4in vane 125 gr heads. My field points fly awesome when i shoot my broadheads g5 montecs they fly left. I've shot paper with field tips my tears are perfect. Any suggestions?
BH's shooting left from your FP's typically indicates being overspined (assuming you shoot Right handed). You need to change one of, possibly all of the following if you want to use the same arrow. Increase DW, increase tip weight, increase arrow length. Any or all of these items should move you back to center assuming everything else being equal. Some people will start moving their rest but that is probably just a band-aid for the real problem. Good luck.
Brad, I might agree, but he should be seeing more toward weak spine out of that set-up with a .400 arrow and a 125gr tip, therefore, I'm thinking maybe he wants to make sure he's using his level to ensure he's not torquing his bow any and see if that could be the issue, and if not torque, I'd move the rest 1/16" or so and see if that brings it in where it's supposed to be. If a bow shoots perfect through paper, but still won't put BH's where FP are for the shooter, and they CAN tweak the set-up to shoot the BH's and FP's together, then I say the paper-tuning is more or less a wasted step. I've attempted to paper tune a couple times with no real success at doing anything but screwing up my whole set-up, so for me, it's a quick eyeball of everything, and then zero a pin, walk it back, then screw on the BH's and make some fine adjustments to get everything where I want it. I just can't see the true usefulness of it when after trying it, it seemed it screwed more up than it fixed. I put everything back where I'd had it, shot a few arrows, fine tuned and my FP's and BH's were together at 40yds, I'm okay with that..... Here's Easton's Guide for reference.... http://www.eastonarchery.com/pdf/tuning_guide.pdf
Did you notice he only has a 27" long arrow? That tells me his DL is also short. I'm guessing he is overspined due to the fact of a short arrow and a short DL. Everything you mentioned could be the culprit as well so he is just going to have to play with it.
