My SBE has never been my best patterning gun but lately there has been a lot interest in the SBE/SBEII and the new Hevi-13 shells.
I have 3 barrels for the SBE, 24", 26" and 28". Here's the 24" pattern.

73 °F
Partly Cloudy
Humidity: 41%
Wind: 8 mph from the East
Visibility: 10.0 miles
Dew Point: 48 °F
Precipitation: 3% Chance of Rain
Pressure: 29.99 in
UV: 11
Thanks,
Clark
P.S. This is the first shot through a brand new SSX just out of the package. The SSX tends to pattern better the more it's shot, so patterns will probably improve over time.
