1 to 2 years ago, I bought some S&B from Cabela's. It was 00 if I remember correctly. It ran fine and performed very much like those above already commented on. Finding #1 is probably going to be more of a challenge, in most brands, from what I've seen sitting (actually not sitting) on the shelves.
Edit: I found the
patterning tests I did using the S&B 00 buckshot, in case you are interested.
