Aside from the few .22 short gallery rifles, the majority of Nylon 66s are .22 long rifle only. There appears to be enough mass and overtravel in the bolt and striker to work with most ammo makers' .22 standard and high velocity rounds with little worry.
I have tried the subsonic craze in mine. Mine becomes a straight pull bolt action with CCI CB Longs (29gr @ 720fps) and is very quiet.
With the CCI Quiet .22 (40gr @ 710fps) mine ejects the empty but I have to retract the bolt handle to cock the striker and release a round into the feedway. I have not tried the CCI Quiet Semiauto (45gr @ 835fps).
