I shot my SR22 a couple of times w/o ear protection in an effort to rid my place of a pesky varmint(unfortunately unsuccessfully) and realized I'd forgotten just how LOUD the little bugger is. It just seems that even with the tiny powder charge in a 22HV, there's a lot of powder burning outside the bore. Looking at how well CCI sub-sonic HP performs from my muffled 22/45, I've decided to try some of that in the little SR and see if it cycles and is reasonably accurate.
I already know the sub-sonic's muzzle blast from the 4" 22/45 open muzzle is approximately at the level of the CCI low noise type ammo but the bullet performance is significantly better and it has the "umph" to cycle the slide.
