I've done some of both, Larry.
It's a better field gun. O'Connor sold quite a few in that very configuration.
Winchester, in their own words... said the WS-1 was optimized for 20 yards, and the WS-2 was optimized for 30 yards. That's one thing Winchester said that is the truth.
As far as being 'set up' for skeet, it ain't.
We both know the dimensions of a skeet field.
It's a good combination for doubles from 4, but that's the only place any choke is desirable on the whole field.
'Skeet 2' as it became known for whatever reason is just one of those little absurdities in life... it does show how people pay attention to ads and the result is that a thing can become engrained in culture no matter how ridiculous it is.
'The Model 21, your gun for skeet' ranks right alongside 'Less filling, tastes great.'
