That chuckhawks article makes no sense to me, as regards the jacketed bullets in CCI WRF ammo. I'll have to research that a bit more. Okay, I looked at CCI's site, and they say that "most .22 revolvers have undersized bores," making jacketed bullets unsuitable. Wellll, maybe, maybe not. Some do, some don't.Back in days of old when I owned a M51 Kit Gun I shot plenty of .22 WRF through it without problem. It was a much more pleasant experience than with the .22 Magnum round. Somewhere I have heard that CCI does not recommend using their jacketed .22 WRF in revolvers, but I cannot quote a source for that information.
Ah, found the article about CCI .22 WRF ammo:
Ammo Roundup: .22 WMR (.22 Magnum)

Did you shoot the Winchester or the CCI brand? I can't find the Winnies rite now, but I'm fearfull of trying the CCIs in my Mod 650.
if I feel the need for a little extra power and not use the 22 mag I use the CCI velocitor as it is certainly more consistent.
Out of a M-48 6 inch the CCI WRF was a 780 low , 988 high , 218 es , 890 avg and 59 sd.
Out of a K-22 6 inch the CCI Velocitor was a 1062 low , 1116 high , 54 es , 1096 avg and a 18 sd.
I also believe the Velocitor is a couple of dollars less in cost.
the Velocitor bullet is 40 grains and the WRF bullet is 45 grains but I don't feel that is much to worry about.
