I tried some 3" #4 Fasteel in my 20 gauge last fall for ducks and geese and was totally impressed!
I only use a 20 for waterfowl and besides my hand loads, I have tried Winchester and the federal premium which I alkso liked, but neither killed as well as Fasteel - it's my goto factory load now!
The patterning was great and I killed birds out to 35 yards without too much problem - I usually keep my shots inside 25 however......

scopes are cool, but slings 'n' irons RULE!
