I'm shooting an old Oregon bow, 67# with 25" arrows Easton CarbonAeros Carbon 500's (7.7gpi). They come out to like 192, plus the 12 gr inserts and 75 grain heads, that's 279grains plus 2" vanes and nock. I'm shooting mechs, punch and cut. I shoot the arrows like a sure thing, but I'm worried that that light of arrow is going to do the job upon impact? Of course I'm going for whitetails. This is my first time bow hunting, and I don't have anyone but the proshop guys to tell me what I should be using, but this is what they said to use, and some guys on here have thought they are too light for my bow, let alone my game??? They fly like nothing I've ever seen, so I'm not really sure my bow is "feeling" anything. Is it possible that I'm gonna blow my bow from practically dry firing these arrows?

Screw the 10 ring, keep them in the zero!!!

Is the 279 grains estimated? If so, you should weigh them. a 67# bow should be shooting nearly 350 grain arrows. You should have left your arrows longer if you thought they would be a problem. Use heavier points if possible, and lower your draw weight. See what they weigh first. My father has similar arrows and they weigh 360 grains at 28" with 125 grain points, and they are spined for 55# draw weight. Good luck.

I think the 500 series arrows are to light for the poundage your shooting,just my opinion.I would think the 340's or 400's would be better for hunting,as long as your bow shoots them,they would be stiffer in spine and heavier in overall weight for better penetration.I would prefer shooting a little heavier arrow at game,this is only my opinion.Can't give you an opinion on mechanical broadheads,I havn't had any experience with them.Good luck,you might want to check out the Easton shaft chart to get the right shaft size for your draw length and draw weight.
