.22 LR is so cheap and available compared to .22 magnum, that I would prefer the .22LR.
.22 LR production is finally satisfying demand. Prices will drop over the next year.
The magnum out of a pistol only gives marginally better performance than the .22LR.
The .22 LR is much easier to suppress, as well.
3 .22 LRs are equivalent to a 9mm. A thirty round magazine is equivalent to a 10 Rd 9mm magazine for power available.
This year I have only a few new firearms planned, but I'm watching the HPA and will plan accordingly.
I've always considered the SR-22 a nice new design from Ruger, who has never sold me a bad/marginal firearm. Maybe it wouldn't hurt to just put one on the list.
With, not without. :)
