Super String Theory
An afternoon on the range tuning a couple of Pitbulls for customers showed me for the first time how very effective the HUMA regulator really is when installed in a Bulldog. Combined with our Extended Reservoir charged to 4000 PSI, the results pretty much speak for themselves. I was shooting 160 grain Pitbull Hollow Points, the heaviest slugs you'll find out there that can fit inside the Bulldog magazine. A 10 shot string produced an average of 788 Fps and 220 Ft Lbs energy, with a very respectable ( for a .357! ) extreme spread of only 17 FPS.
