Thread: I have this old Remington 870 Wingmaster....

Found a few things about the wingmasters. This sort of thing popped up several times but while a copy of someone elses correspondence, it does come from Remington.
about half way down the page it says everything since 1950 is good for steel even full choke but don't go over #2 if that's the case.
I think that's a little optimistic as you would want something a bit more open for steel regardless
Everything from 1990's (or whenever lead over open water in the US was made mandatory) on should be fine also but I still wouldn't use steel if its a full choke
