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!!!
