Hi -
I have an older Wingmaster 20ga. It has a barrel marked for 3" shells, but I know the receiver was only built for 2-3/4' (serial number ends in X).
I've gotten the idea from other posts that the only problem really is that the ejector will get stuck. Is that true? Can I put a different ejector in there and shoot 3" shells?
