I just bought one last year at the end of the season,I have been trying different slugs and the one that shoots the best out of mine is the winchester Partition Gold 2 3/4 in 260gr 1900 fps.2in high at 50yds shoots about 1in high at 80yds shooting 1 3/4in group.I would like to try out to about 150yds just to see what it would do, have to wait till the bugs die off a bit.
