If you go back a few years there was a 10/22Mag would have to be found used these days
H&K also made a very good semiauto 22 Mag would also be used market.
Bruno made one as well, again used market Magazines for this one run about $100 these days if you can find one.
One I know of still in production is accelerator rifle link
Excel Arms makes one that is accurate, heavy barreled and most of the weight is in the barrel. I have the 17HMR version of this one and it is very accurate.
22mag semiauto handguns
Excel also makes a handgun
AutoMag used to make a 22mag semi handgun and see them sometimes at gunshows and on gunbroker
