Is it accurate? Yes. Is it Durable? Yes. Are the blades sharp? Yes. Like no other. Does it penetrate? Yes. Like gang busters. Does it kill quickly? Oh yeah! Does it leave a tremendous blood trail? Yes. Blood paved highway! Does it go through bone? Yes. I have been bow hunting for more than 30 years and have never been this ecstatic about a broadheads performance. I've been shooting mechanical heads for 16 years with very good success. I've tried a couple of designs that were not good. I've tried quite a few brands that excelled. I have never until this season decided to try New Archery Products. Oh the time I've wasted! I have killed two deer this year so far. A ten point with the Double-Cross (very good performance) and now a large doe with the KillZone Maxx (extreme performance). I the doe I shot was quartering away slightly and the arrow blew through and center-punched a rib on the way out behind the off side shoulder. The entry and exit wounds were tremendous. The blood trail was awesome. She went 60 yards. Here is my set-up. Darton 3900 @ 29" set at 65 lbs. Victory Vap weighing 357 gr. Shooting 340 fps. This is admittedly a light arrow but at that speed and with the small arrow, penetration has been NO issue. I will be shooting this broadhead much more in the future.
