Thanks Paul! I have some 330s laying around. Wasn’t sure if I’d be able to go heavy FOC or if I’d need to get a stiffer spine

I would think up to 200-225 point weight, if ya can shorten it a tad more say 27.5"s you can easily go over 225 point weight. I shot 27.5" .400 spine out of 65-70# bows with 190 grain point weight for a lot of years. Shawn

What would you say total weight was Shawn? I could shorten to that no problem. No inserts in yet

Depends on GPI of shaft. With 225 you will get over 500 grains on most .330 spined arrows even cut to 27"s or so. Shawn

My 330 injexions weighed around 480 I believe at that length. That was with titanium inserts, four fletch and wrap.
Of course, since they discontinued them, they’ve become harder to find.

Easton Aftermath 340 spine with easton 75 grain brass insert will weigh 497 grains with a 125 grain point . Great arrow for middle of the road with a nice 17% FOC

Also need to know what kind of rest you're shooting and if you use a release or fingers.

Switching to drop away rest. 28.5 draw. Trigger release. My GPI is 9.6

I would say somewhere around 450 grains. I don't think you could load the front up that much at 65 pounds. If you cut an inch of arrow length off, maybe. But I think you will need to use standard inserts and at most a 125 grain head.

You can load the front a ton on those arrows at 28"s or less. I have shot 190 grains of point weight out of 67# bow and a .400 spine arrow cut to 27.5"s. They spine plenty higher than a .400 spine. As I said 225 grains up front cut less 27.5"s and they will spine fine even out of 70# bow and that will no doubt get you over 500 grains. Shawn
