TulAmmo is made by the Tula Cartridge Works. They used to be the main supplier for Wolf ammo, but have since been marketing it under their own brand name. Generally I reserve the steel cased Eastern Bloc ammo for Eastern Bloc firearms, but with that said I think they've improved the quality of their product over the past several years and I don't think you have anything to lose by trying a box or two.
Recently I tried some Wolf Polyformance .45 Auto in my SIG P220. I had no issues, and it seemed about as accurate as any other target fodder. I ordered a few more boxes of Silver Bear in .45. Both Silver Bear and the Wolf Poly are made by the Barnaul factory, so they differ only in packaging and type of case.
There's two main things you will hear repeated about Russian ammo, given as reasons not to use it. One is the claim that the lacquer coating on the steel cases will melt and gum up your firearm. The other is that the steel case will damage your extractor. Both of these claims are false. Regarding the lacquer, for one thing they seldom use it anymore and have instead switched to some type of plastic/polymer coating, and even with the lacquered cases you cannot get that lacquer to melt even with a propane torch. As for the steel case allegedly damaging extractors, the steel used in the cases is very mild steel. It is nowhere near as hard as the tool steel an extractor is made of.
There are people who run training centers that go through a high volume of ammo, and more than a few of them use the cheap Russian ammo without any inordinate amount of problems.
