while my compact has eaten everything so far; overall my best success (in general for any of my .22's) has been with the different variations of mini mags. So for some reason if my .22c was the only thing handy for SD it would have mini mags in it.

That said, as .22 rimfire can really have some issues with ammo that can vary from gun to gun even in the same model; I would suggest that whatever ammo worked flawlessly in a given compact would be the first choice to consider. If someone has trouble with mini mags plinking at the range, i sure wouldn't rely on it for a SD situation.
