Shooting clays this afternoon. One of the fellows on squad was shooting a Winchester SuperX 3 20ga. Nice looking gun with a matted silver grey barrel & receiver. It was throwing empties " a mile". He said it would shoot anything and let me shoot a few of his 3/4oz reloads. Impressive!!! Invector + CT's. Said it came with all sorts of shims to fine tune stock set-up. Any experience among the readers here?
