They are shooting well out of 3 different 7 twist 18" AR's ranging between 1/2 and 3/4 inch. I haven't weigh sorted, just shot them. They seem pretty happy with 25gr. of Tac, Rem 7 1/2 primers and L.C. brass. Surprising bullet really. Will be using them for coyote this fall... Has anyone hunted anything with them yet ? Hornady says hunting bullet if cannelured so...thinking they should work well for coyote. Expecting normal hole in and small out....but that's a guess. Any gel tests or... ?
