The only thing I shoot Wolf ammo in is my CZ VZ58. It was made to use the commie stuff. It is dirty ammo for sure. I've never even considered using Wolf, Golden Bear, or Golden Tiger fodder in any of my HKs. It is getting expensive to shoot my USC and 91 for sure. If you can find it try getting some Blazer Brass for your pistol, or 94. It's decent ammo and can be had a a fair price. Walmart carries it... when they can get it and the 9mm sells for something like $8.57 a box around here if I recall correctly. I've used their ammo in my all my HKs from the 9s and .40 through the .45s. It's cleaner than the Winchester White Box and accurate.
