This would be alright in a war where one side is using NATO small arms and the other guy is using East Bloc arms. But in Syria both sides are using the same weapons and ammo. It’s like poisoning a well. The other guy can poison your wells.
I think I would just pull every bullet in my combat load, inspect the powder charge, and reseat it with an improvised reloading press once confirmed safe. It would take some work but soldiers have to work hard before and after the battles too. As I recall, the Angolans had to do something along these lines.
