Scott, I am, admittedly, a huge BSA air rifle fan. I have not shot a Super Ten, but have done a lot of research on them. The Super Ten does develop good power, in the 30 fpe range in a .22. Yes, the Super Ten is a regulated rifle, and from what I have read, it works well. I have read of typical BSA accuracy with the Super Ten, which means very high accuracy. The only few less than positives I have heard from Super Ten owners has been that the design is somewhat front end heavy. The Super Ten uses a "buddy Bottle" air reservoir. The bottle has to be removed from the rifle and I have heard that some folks have had problems with resealing at the O-ring that seals the bottle to the rifle. I have also heard the keeping the O-ring on the bottle clean and lubed lightly with diver's silicone grease can help with, or elminate the sealing problem.
