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.
