I shoot the 125gr. 3 blade Magnus Snuffers and many other guys here on Trad Gang shoot them as well. I don't really see any difference in shooting a 3 blade Snuffer or shooting a 3 blade Muzzy?
The only real big difference is that the Snuffers are meant to be resharpened, but it still takes a certain amount of KE to push them through an animal. I zipped one through the shoulder of a coyote and it sliced through like he wasn't even there, then buried in the dirt about 4" on the other side. I know that coyotes aren't as heavy boned as a deer, but I had more than plenty of KE to blast through the coyote and then some, so if that's any indication of what it will do on a deer, then I'm not worried at all about shooting a 3 blade broadhead.
That's a heck of a deal on the Muzzys, I would definitely go for it and like one of the other members already said, "I'd buy the whole shelf full for that price" +1 on that!
Even if you decide you don't like how they shoot, you could turn around and sell the rest and make a buck or two.
Muzzy broadheads have killed a ton of game and are one of the best quality broadheads on the market today and it's a good ole made in the USA product......that's a rarity these days.
Here's a final thought.......Fred Eichler shoots them and kills everything from whitetail to goats to bears with them and he even married the daughter of the founder, who is incidently now the owner. Fred said on one of his shows that he got tired of paying for broadheads so he married the owner so he could get Muzzy broadheads for free.
