Alright im shootin 5/16 ramin wood with a 160 head on it im trying magnus 1's but they aint flyin quit how I want them any suggestions on different broadheads,like a left bevel.

First, it's not the head, it's the arrow, the head is only magnifying the imperfections of the arrow.

The 160 might be to heavy for your arrow, you can ether shorten it to make it stiffer, if you have room or you need a stiffer shaft, ( you did not state you bow weight or draw length was).

If you haven't already done some tuning, click on the A & H archery icon right above here, then click on knowledge base, then click on bow tuning.  If you have already done this, i apologize in advance.  Come back with more information if they still aren't flying right...for instance, where are your broadheads hitting as compared to your field points?  There are some guys and gals on here with a wealth of knowledge but they will need some more info to give you an answer.  

Thanks, yea i think i need to shorten them about a quarter to a half an inch, i just need to sacrafice one arrow and play around until i get it right. Also its 44# @28" my draws rite around there with a 29 1/2" arrow.
