That's just what i've tried over the last few years; i've got a few guns with the invector + system and most of my friends shoot brownings, so chokes have been easy to try. but yeah, a bps will punish you.

as far as 3" goes, i normally hunt with a gold classic stalker and that's what i shoot thru it - if i were going to shoot 3s, i wouldn't haul the extra weight of this beast around. just trying to find 3.5" shell/choke combo for this gun. thanks for the suggestion, though.

i originally bought it for duck hunting years ago, but now take the gold or japanese A-5 for that. this gun hasn't seen much action in the last few years, so i'm trying to find a reason to keep it around.
