My new longbow pulls about 48# at my draw length. I'm using 500 spine Beman MFX arrows which according to the chart - a Beman chart specifically for that arrow - is the proper spine. I've tried tip weight combinations (insert plus field point) from 150 to 250gr. I started with full length shafts and eventually cut them down as short as I can get away with. I don't see any way these shafts could be weak. But when shot - with every combination- the nock end whips wildy to the left before straightening out. I thought it might be a form/release flaw but I went back and shot my other bow and the arrows fly straight. Any suggestions of what I should try next?

Let us know what you figure out when you get it dialed in. I have nearly the exact bow specs that you have but I shoot easton axis 400's cut to 30 3/4" (BOP to throat of nock) with 175 grain points and standard HIT inserts. They put absolutely perfect holes through paper. I tried some beman 500's cut to 30" when I was tuning that put great holes in paper but I can't remember with 100% certainty whether I was using 175 or 125 points. I'd have to shoot them to find out.
What is your nock height set at? That was my biggest problem when I was trying to tune those small diameter arrows. I shoot three under and most of my setups have 1/2" nock heights but for some reason I had to go up 9/16" with the small diameter arrows on my recurve.Last edited by EnW; 10-18-2011, 09:03 PM.

It can be frustrating, been there. As others have stated it could be your nock point. Arrow may be kicking off shelf. Brace height could be contributing to it as well. There are so many things that need to come together to make it shoot right it's easy to get off track. I went thru the bare shaft planing method several times before all the pieces came together for me. BTW, my bare shafts still kick left(actually 10-11 oclock) in flight but hit with my fletched arrows. 165gr Sharks hit with field tips too. If you can't make it down to see Mike, I'd be more than happy to help. Just let me know.

Hi John,
I'm not a lot of help in this department, but I have close to the same set up. In my Beman 500's I have a 100 grain brass insert and a 175 grain point, for a total of 275 grains up front. I shoot these arrows from both of my longbows and one is 45# and the other one is 49#. It sounds like we are close and the only difference is I had to lower my brace height a couple of twist on the 49# bow. You might just try a little more weight in the front end, because mine fly true with this set up.
