Has any one tried these, how do they shoot and are they sharp.

Like any broadhead you will have to tune it but I really like it. Nice big cut and amaizingly no drift. I also have Blazers so that helps a bunch. Make sure your bow is completely tuned and ready for you to start shooting broadheads. If not then you will pull your hair out. JMO and experience. Best of luck.

I just opened a pack of MX-4s this evening to try out. I was using the practice blades and I had no tuning issues whatsoever. Mine shot great and I also use the Blazers. They flew as well as my Rocky Mtn. Turbos.....the best flying fixed blade head I have ever shot. I didn't have some 4" feather fletched arrows with me at the time to shoot. They should shoot as good or better using the real blades. I will now officially carry 2 Muzzy MX-4 and 2 Rocky Mtn. Turbos in my 4 arrow quiver.

No flight problems with mine. I love them. Can't wait to try them out on a big IL buck.

I like mine. I shot them last night with the practice blades for the first time. I still have a few tuning issues to work out with them but they do seem to work well.

Time to buy a Yellowjacket. They have basically turned my current target into shreds.

I can only imagine what they will do to lung and other various tissue.

One final note, my bow is tuned pretty well and they fly real close to FTs. Do yourself a favor and make sure your bow is tuned properly before shooting the MX-4's.

Well I have 2 nights into trying to tune these things. Last year I was able to get my slick tricks grouping with my field points pretty quickly and easily. These Muzzy's are a different story......they are a bit erratic it seems. I am going to put in another good tuning session this weekend when I have more than an hour to put into tuning and see what happens with them. I may grab another pack of something else tonight at the shop though to bring to PA this weekend when I plan on tuning in case I can't get these muzzy's to at least group. I know the bow is in tune as well..........it walk back tunes, line tunes vertically and horizontally, spines good on OnTarget2, and paper tunes. The arrows also spin on both ends very well so I I am really questioning these heads at this point............

Like I said I will be putting in more time this weekend to see if I can dial them in, it is critical that any fixed blade head I have shoot w/ fieldpoints because I shoot a mechanical 99% of the time but need a fixed blade to go to when I am in the ground blinds shooting through mesh.

The mx-4's worked great! I was fortunate enought to take a bull elk with these 100 grains last week. THey definately eat up some meat!
