Don' t ask me why, but my friend was a tried and true Muzzy believer until this year........He got some Magnus Stinger 2 blades with optional bleeder blades, and he shot a field point arrow into the target, shot a Stinger arrow into the same spot, and the blade was somehow turned vertically and slid right along the shaft of the field point arrow. Shafts touching. He said he' s always had to adjust his sight for other heads, but he didn' t with these, and they hit like a TRUCK he says!!!! They' ve already downed his doe, and a couple friends' 10 and 16 point bucks. One guys said with a less than perfect hit it left a bloodtrail a monkey could follow. And they STAY sharp!!!!!!!!!!!!!!! He' s had it punched through a broadhead target LOTS of times, and he shaved his arm with that broadhead for me. LOL I kinda became a believer, and I' m gonna get me some when I get some more money. They are a cut on contact head, and the whole main blade can be replaced easily if needed. Also small bleeder blades are optional. I' m gonna give ' em a try and maybe post a review.
