Here are some chrono results from the one I picked up yesterday. Just for kicks, I have a whole bunch of chrono data that some of you might find of interest. These were all shot today at 5950' above sea level, at 65 degrees Fahrenheit and c.15% humidity. (I ran a check with the 22/45 and Automatch, a known gun/ammo combo, and the chrono readings were on.) All these numbers from the SR22 . . .

Now. The Federal Automatch had failures to load rounds into the chamber; despite the decent velocities given, the recoil impulse wasn't enough to render this ammo reliable. The Aguila SSS was (surprisingly) completely reliable in function and not bad in accuracy - and phenomenally tiny in spread from this gun. Everything but the Automatch was utterly reliable in function - weak hand, strong hand, both hands - the gun just worked. The Winchester Super-X (which has uniformly sucked out of every handgun from which I've tried it) was inaccurate and had large spreads. The Aguila Super Extra Alta Velocidad (which is not the same as their SE Super Extra subsonic 40-grain - crazy naming of ammo) was more accurate than their Interceptor. Quik-Shoks continue to impress as more accurate and consistent from a handgun than the same weight hypervelocity Stingers.
I put about 250 rounds though it - and it cleaned up easy as pie. Can't wait to go back out with it.
