Mechanicals work great if they are flying out of a tuned bow. IMHO, it's all about putting in the boiler room. Since starting to use mechanicals, I haven't lost a deer, and spend more time shooting versus tuning. I shoot field points all season. Shoot my Jakhammers a few times at a few distances, and go hunting!

Your arrow is under spined. The chart for your arrow is 31'' 65 pounds 300CX, 32'' nextlength is 400CX. I always go a little stiffer. I think you have couple choices. At 31.5 you are stuck right in the middle.

1.Buy 400CX
2.Go to 100 grain broadheads and fieldpoints
3.Shoota shorter arrow

That's my thought too ghemry, but he states the group great, just right. Usually an underspine you'll loose the group with a fixed head. Are you left handed by any chance?

I am LH, but I do not think he is underspined that much. I bet if he went to 100 grain headshe would befine.

ghemry.... I didn't mean are you left handed.... I meant Kansas.LOL We're trying to solve his problem, not yours.[8D] I agree with the underspined. Even if you go to their site and use their calculator and figure fast flight string etc etc it says so.

I know, I was just letting you know, I have no problems!!!!! LOL

NAP Spitfires work for me as well

First let me clarify, my draw length is 31.5, I am shooting an overdraw w/ 29.5 arrows. Over the weekend I had 6 arrows refletched w/ feathers. That took care of all of my hits to the right-makes me think there might be a little clearance problem, but I can't seem to find it. The broadheads I am currently working w/ are thunderhead 125s & muzzy 100s. At 20 yds, it seems the muzzies are slightly more consistent, but not much difference at all. Right now I would be very comfortable w/ either broadhead, but I will continue to tinker @ this range until after my bear hunt in 2 weeks. After that I will move back to 30 & 40 yards to see if they continue to fly as well down range. Thanks for the input & don't stop replying if anyone has any ideas on fine tuning my setup.
