Is this strictly a revolver round, or does it cycle semiautos?
No, it's not strictly a "revolver" round at all. The CCI Quiet ammunition functions just fine in bolt action rifles, AND, if you have your Ruger semi-auto set up properly, it will cycle and function just fine with the CCI Quiet rounds, even when the pistol, or rifle is suppressed.
The bolt in this Ruger Mark III 22/45 is a "prototype" part still in the beta testing stage. Weight of the above bolt is less than half the weight of the factory Ruger Mark pistol bolt. This pistol shoots/functions CCI Quiet @ 710 box velocity very well. The barrel on the above pistol will not provide that velocity as fired over my Oehler 35P chronograph, yet the pistol still cycles just fine.
Same goes for the Ruger 10/22 platform. Get the proper BOLT, and you'll be able to shoot CCI Quiet ammunition, again, even suppressed, out of your Ruger 10/22 rifle.
There's no sense in pouting about CCI Quiet ammunition not being available locally, if one were to go on-line, there's a plethora of .22 rimfire ammunition that's available, even the CCI Quiet stuff.
