Yesterday the TEA party hosted a silencer demonstration at the VFW post in Cumming.
They tried to get a Ruger MK4 pistol in .22lr to work as a semi-auto with CCI Quiet ammo (710 fps) but that cartridge would simply not cycle the bolt. The shooter had to manually caulk the bolt in between shots .
With standard velocity or subsonic ammo (1030 fps), the pistol cycled just fine .
