Been on a 16 gauge kick for a while now and a while back I bought an old Stevens double, older than the 311 I think, but looks similar, in 16 gauge and just finally got around to shooting it today.
The little gun patterns well, I'm sure the chokes are improved and modified based on barrel length and the left barrel was definitely a tighter pattern than the right. The problem is the bulk of both patterns was maybe 8-10 inches left of where I was pointing. Pattern was correct up and down, just left.
I looked close and can't see where barrels may be bent. the front bead looks a little off, but not much. Could this be a stock fit thing for me, too long or short? I am far from being an expert on shotguns, and want to become more proficient with this one.
It's a neat little gun. I took it out to do a little scouting and checking on my deer stand before opening day Wednesday and it got soaked in a rain and sleet storm I got stuck out in. It's disassembled now with the action soaking in some Ed's Red. I should probably refinish the stock while I have it apart.
