Wolf is steel case polymer coated ammo. Barnaul, Brown Bear and Monarch are all lacquer coated steel case ammo. Golden Bear is brass coated steel case ammo. None of the coatings is the problem with steel case ammo, it's the steel case. The steel doesn't expand as far as brass so some of the carbon from the barrel blows back around the steel case and sticks to the chamber wall.

If you use brass case ammo after using one of these you will probably have a stoppage. The brass expands as it usually does and the carbon from the steel case ammo will stick to the fully expanded brass and fail to extract.

Some AR15 type weapons will work with steel case ammo and some will not. There is no way to know if yours will unless and until you try it. I recommend that any person new to the AR15 platform or using steel case ammo for the first time to buy only one box until you have tried steel case ammo and have found that your rifle or carbine will function with it.
