I inherited a nice little 870 wingmaster 20g in a house cleanup and I am looking for suggestions for a decent waterfowl load. Has to be a 2 3/4 and steel/ non-toxic shot. Everything available off the shelf here is 3" and the only steel #4 I can find is Winchester DryLok from Cabelas. Any other suggestions so I can open up the variety a bit? All of the 2 3/4" here is lead and that's a no-no for birds up here. It's a nice clean little shotgun and it will be a hell of a lot nicer to carry around than my 12g if I can find the right shot for it.
