I shot my first shells through my new-to-me 2E 20 gauge, (1909 vintage). One barrel appears to be full choke, the other must be cylinder as the pellets were scattered everywhere over a 5 foot circle. This is the loosest choke I have ever seen. I tested the gun with polywad vintagers, does anyone have any recommendations about methods to get a tighter pattern? Any advice is welcome. Rob.
