Eh, you know, with a hit to the torso its pretty academic from rifle calibers like 7,62x54R or .30-06 onwards, you'll be incapacitated at least, I would not want to get shot by a .22...
Reality and this game are two different things tho, and authenticity should be secondary when it comes to gameplay/balance.
Well at least it is a slight improvement from before, where guards would stand in front of a 222, miss every PTRS shot, drop the PTRS and get wiped on retreat. I haven't played with them yet so I have yet to see if they are as OP as people assume they are now. They probably still are weapon drop piñatas so there's that.
