I shoot a 60 lb. bow with the Rage 2 blade - and had the chance to test them on two big mulie bucks last year. One was a pass through and the other stopped in the off shoulder. Both deer were only able to go about 50 yards after the shot.

One of my buddies had a whitetail buck jump the string on him last fall and wound up with a center gut shot. This buck also was on the ground in about 50 yards - apparently hit some big artery in the paunch area.
