I got a new one from a pawn shop a few months ago for a heck of a deal.
I deep cleaned the bore really well and I also made sure to tighten the cap down a few extra clicks past hand tight when I re-installed the barrel.
Out of a clean bore, using an ssx .643 choke, it shoots the Hevi 3.5" #6's extremely well.
It also shot to point of aim exceptionally well.
It shot so good, I never tried any other chokes or loads.......
