Mine has had the forcing cone lenghtened and the barrel polished. I shoot an Indian Creek Black Diamond with Winchester Extended Range #6's. It's murderous out to 50 yards. It is a circa 1989 model with the laminated hardwood stock.
Got 221 in a 10 inch circle and 440 in the 20 inch circle at 40 yards using a PG .670 and #7 hevi shot. That little 22 inch gun flat out rolled 2 longbeards at 38 and 42 yards last Spring.
both my brother and use win 1300's, and they are partial to win supremes 1 3/4 6's ... he uses a hasting's 640 and i use a kicks's 640. next would be fed #5's out of mine and win #4's out of his
