I shoot a 430grn +/- arrow including my 100 grain, 4 bladed Wasp Boss SST fixed blade BHs, who's cutting diamter in 1-1/16". My speed is I THINK IIRC, around 260-265fps (been a looooong time since I shot through a crono) out of both my Darton Maverick RC and my Tundra. Both set around 66-68lbs, and my DL 29.625". I shot a decent buck who was quartering towards me at 23-25yrds. My above arrow set up broke through his front shoulder blade, went through both lungs, and snapped a rib in half before exiting and going 4-5" into the ground. He instantly trotted for about 50 to 60 yards and then just dropped. Left what I like to call a "Stevie Wonder" blood trail. Left golf ball sized entry and exit holes.
I went to the 4 bladed Wasps on a hunch and they darn near doubled my max range with no other adjustments to my bow. They are also about as close to "BOMB PROOF" tough as a BH can be. I have accidentally shot them into the steel unistrut that sandwiches my DIY target more than once (the strut is now wrapped in 5-6 layers of carpet) and every time the Wasp Boss remained 100% intact not to mention they actually stuck into the strut and pennitraited up to about a the first 1/32 of the blades. Also once (don't ask how, but I wont ever put a target on one again) shot one through a 55 gallon steel drum. Went through the first side and almost 90% the second and was still in one piece even after I removed it.
I even used them while hunting elk, but wasn't lucky/good enough to get a shot.
What I love most about them is they fly superb 99.9% of the time shot after shot. They gave me a HUGE confidence for shots on deer. LOVE my 4 bladed Wasp BOSS SST BH's. FWIW, tried Slick Tricks, but out of both MY bows the Wasps flew better.
