I have a M37 in 16 gauge, along with a rifled slug barrel. Gun is quite accurate with Brenneke & Remington foster slugs. Still haven't taken a deer with it yet, though. I have taken ducks with it, as well as all manner of small game. If you reload, you can open your patterns up a bit with some spreader inserts in your loads.
Have fun with that new 16 gauge!
