i get about 2-3 in groups at 75 yards, and that is on a shaky rest,as that is where i site mine in at, as i usally don`t shoot much farther than that, this is the load i used on my old muzzy, and when belive it or not, on the first shot with open sites,i hit the bull, and i though i missed the target, as i dodn`t see the hole.lol
only trouble i have had i one time when i shot my first buck with it, it opened on the shot, i thought i might have hit the button but not sure, hasn`t done it sense.
i have read alot about 777 leaving crud,i shoot 777pellets do`nt really have any prolbems, but i don`t shoot alot between cleaning..
good luck with.
