Bob, Stan,
Both guns were 20ga with 28" barrels.
Let me count the ways;
1. Browning was "clubby" feeling as mentioned above, Model 23 was a more fluid handling gun with more of it's weight between the hands
2. Model 23 was better looking
3. Used both on grouse and pheasant hunting. From a walking/ready position, Model 23 came to the shoulder/cheek smoother and scored more often.
4. Patterned both and the Model 23 had more evenly distributed patterns with both size 7.5's and 5's.
Outside of that, there wasn't any difference!
I've nothing against Brownings and own several. The BSS just didn't cut it in comparison to the Model 23.
Now if I were to have to choose which of my guns I'd keep to the end, A couple of Parker Reproductions would get the nod.
