I have acquired 2 boxes of 16g upland loads. maybe 3 shells missing. I dont have a 16 and no one I know does.
Northern NJ face to face. not interested in shipping... not really worth it for 2 boxes.
If you are interested in a couple boxes of factory 16, I would gladly trade for .22 rimfire, 30-06, 12g, .410, or 7-08. Or lead. Or just a couple of good cups of coffee.
