Little tiny 100gr cut on contact Sonics.
I've shot them to 55yds and they fly and group right with my practice field points. I don't know of any other broadhead that can do that. Therefore, I don't have to 're-sight' in my hunting blades before going afield...
You might not think they'd kill so well for such a small cutting dia., but I've got no complaints so far and plenty of vension in the freezer...
