Clarification...
Just, for the record, CCI produces the "Mini-Mags" in two versions. The 40 grain (copper plated round nose) with a 1235 FPS velocity, and the 36 grain (copper plated hollow point) with a 1260 FPS velocity. THESE ARE THE ONLY TWO VARIETIES OF MINI-MAGS.
CCI also produces the "Standard Velocity" LR round, with a 40gr lead round nose bullet with a 1070 FPS velocity. There is no such thing as a "Standard Velocity Mini-Mag".
The S&W 22A is an alloy frame firearm, which I understand, has now been discontinued from the S&W lineup. Seems a shame since mine has been a great gun. Very deserving of it's reputation as the "poor man's Model 41". Virtually every "wear part" in the 22A is easily replaceable. The fiber buffer is something to watch carefully.
With all that said, it seems counter-productive to feed the 22A a steady diet of high velocity ammo (Mini-Mags) when the Standard Velocity (SV) rounds work perfectly well, and are actually a bit more accurate than the MM's.
Just my .02 worth.
