I just picked up my new 82nd yesterday and she is sweet. The Birth Certificate states 61lb, 29inch doing 336fps with 300gr arrow. I have it set up with a 30 inch draw. I tried about 3 shots with a 300 garin arrow through my chronograph and the speeds ranged from 346.3fps-348.8fps. It was smoking fast at 61lbs with an IBO arrow. The Carbon express Maxima 350's that weigh 397 gr were doing about 303-305fps. My easton st epic nfused 340's which weigh 437 gr were doing 287-290 fps. Both arrows group great. My question is, of the two arrows which ones would be best for whitetail? Based on everyones experience, would I get a passthrough on a deer let say at 30-40 yards I hit them in the vitals broadside?
