I have been using Muzzy s for over 10 years and they work well shoot straight and are durable I used the same mx 4 on 3 does and 1 buck this year just replace the blades and it was good to go . The buck i shot last week was a mature 200 pound buck my Muzzy passed thru slight quatering and he ran around 100 yard only because he was still hot on the heels of the hot doe in front of him
