The IDF used custom 10/22's to take out known Pali terrorists. They would aim for the leg, hip, and area's like that to wound them and remove them from the action, usually from 50 to 100 meters.
Then some of the snipers started aiming for the upper back, neck, shoulders and such and ended up killing the Pali's. For some reason, either the politico's or IDF command stopped it.
This is one of the sites where there is info on the IDF using 10/22 rifles. I'll see if I can find the other.
IDF 10/22 Sniper Rifles
Oops! I missed your post while I was blathering. Nice link. My son has a class III license, so I've fired several suppressed weapons. My fav is the MP5K in 9mm, suppressed. A real lead spitter!
