This is my first time suppressing rimfire, I've never bothered with .22s before but they seem to be so much fun suppressed and good to get the kids going on.
I have some of the federal 325 packs of "standard velocity" ammo advertised for use with semi autos, stated velocity is 1200fps. I thought maybe out of a pistol this would be subsonic but my first trip to the range says, "no". I have a GSG 1911 so 5" barrel and there was definitely a small crack witch each shot.
I have some CCI "Quiet" but at just 710fps I don't think that will cycle a pistol.
CCI has both "subsonic" and "standard velocity" advertised within 20fps of each other at 1050 and 1070 fps respectively and these look like good bets but could potentially be supersonic in colder weather from a rifle, no?
What is everyone using for subsonics in both rifles and pistols?
