I know that .22lr is too weak but Is a .22wmr or .22 mag a viable

Better than nothing but aside it's low power it's also rim fire, something you'd want to avoid.
Let me guess you want a PMR30? They are fine to plink and snag varmints is it better than no pistol? Yes. Would I suggest it? No.

No
That being said, 5-8 rounds of anything in someone's chest will ruin their day

I live in a cucked contry and don't wish fo be put on a watch list for buying a high powered rifle.

I know some people in police and they say that they keep an eye on anyone that buys a "high powered semi automatic rifle"

Then buy a high powered bolt action rifle. If you are in Europe, CZ and Tikka are your best options.
