I picked up a Winchester SX1 at the show this weekend and took it to hit some clays yesterday.
All I can say is wow! My first semiauto shotgun and I was very impressed. It was kind of dirty when I got it and went straight to the range. No stovepipes and no feed issues using RIO #8 1.125oz (100rounds).
I did notice that when loading the tube the loaded round tries to push out. Is that normal?
