Milsurp After Hours

Looks like in Isreal they decided to use a 22 sniper rifle as a step up from shooting non lethal rubber bullets. Then they discovered what they should have realized to begin with. A 22 isn't a toy and can kill people just as dead as the larger war gun calibers.

A little knowledge is a dangerous thing, particularly when you're using a dangerous thing.
They ought to have read about French resistance fighters taking out German soldiers with single head shots with .22 rf.
It was apparently one way of getting a nice Mauser.
