When I was a kid, I received a Belgian Browning T bolt 22 for Christmas one year. Dad brought home a spam can of russian 22lr, it was in a blue and white 50 rd cardboard boxes inside the can. Shot just fine, absolutely filthest stuff on the planet. Extremely greasy/waxy to the point you would have to continually wipe your hands on a rag after loading each time, haha. Left the bore filthy as well, also smelled terrible when fired, but it always fired and the price was right, seemed accurate enough.
