Most other semi-auto rimfire rifles and handguns won't cycle that or anything like it, such as CCI Quiets, in my experience.
Now, as to the OP's issue: Can't say much to help on the 10/22, but for the MK IV, break it down, then clean and lube, as @dlbleak 's post above. Use a light oil, absolutely no grease or motor oil. Something like Rem Oil or any other really light oil. It doesn't have to be dripping wet, just a light coat of light weight oil is fine. Then run a couple hundred 40 grain CCI Mini Mags through it. The 40 grain round nose is best; they will just perform just a tad bit better than the 36 grain CCI HP's for this purpose, IMO. After that, repeat the clean and lube process and see how it's running. If that doesn't work, bring it to me with all your .22 LR ammo and I'll take it from there.
In all seriousness, my MK IV will cycle about anything now except the CCI Quiet and similar really low-powered ammo, like the Aquila sub sonic rounds @emapples had a problem with. If you'll do as suggested, yours should to.
Your right , all the subsonic rounds won’t cycle but I wonder how much of the issue is just poor quality control from 22 lr manufacturers and how much is the weapon.
I’ve been using the same Product for 10 years it leaves a very fine film ......I had good luck with it and just never used anything since. I still have some Hobbs and Remington gun oil but this stuff has done the trick since I started using it.
Since being inflicted with GA Syndrome I keep several cans around
