For Pete's sake, don't shoot Wolf in a US/ Euro model gun. It is the dirtiest, nastiest stuff you can buy. The cases are brutal on extractors that are designed for brass. The only thing I would recommned Wolf for is Anything Kalishnikov (AK)
. Wolf has a gold line, but I will bet you a beer that the same powder goes in that brass case as does the steel stuff. Did I mention it is the dirtiest ammo I have ever used?
Any quality production ammo is OK. I have read more than one bad experience with WWB ammo though. I used to shoot it because of the price, but now it has gone way up too (Wal Mart).
