well, I've had the last couple weeks off and its been cold so I've had the chance to mess with my stuff alot, besides putting together the arrows above I also put together a few test 2213's
I shoot 85gr thunderheads out of my vertical bow and really like them, however I really DONT like the 125gr thunderheads I bought for my crossbow... I gavethree of the 85gr thunderheads to my son and kept three for myself in case I get the urge to hunt with my vertical bow, but I got the brainstorm ofrigging up some more inserts to be used with the 85gr thunderheads and my crossbow, and they came out very well
this is what I came up with... 2213's, 85gr tip, weighted insert, cut down insert for nock(13gr), and feathers came to 435gr OA with a FOC of 17.3% with the thunderheads(according to that FOC calculator...

), stat-wise they turned out to be an almost exact copy of theabove carbon arrows...
unfortunately I still havent gotten to shoot either set and I'm pretty excited to do so, but I'm not wading out in the snow with my crosbow and target to do it, I think I may have to go to the local range this weekend...
