I shot a Parker feather mag at 62 lbs. with Easton epic 500 at 26.5 inches which weigh 344 grns. this year. I have a 27" draw length and the parker is no speed burner. I used the Rocket steel head 100 and it blew thru a doe at 25 yards and I watched her fall after going 50 yards. With good shot placement, this combination seems to work very well. Don
