Slick Tricks are much better that Muzzy (I've used both). They have bigger thinker blades that won't bend and they can be resharpened.
GFY.
Ok. I admit, I would use them too, but i can find six packs of the old 90 grain 4 blace muzzies on E Bay for like cheap. The last 13point buck and belligerent bear that i dealt with made it about 18 steps.
Brothers last 2 bull elk, a 7x5 and 6x6 didnt fair much better.
He got me on them them and they may have saved my life with the upset bear that came for me.
