I've only shot about 100 rounds of it, through an SKS and a WASR-10, and haven't had any problems. I haven't noticed that it's any cleaner than the old stuff, but I also didn't think the old stuff was as dirty as some people have experienced. I'm not a good shot with iron sights, but I can usually hit a dinner plate at 100 yards with the Wolf from a standing position. Haven't tried any in my AR yet, but for the Combloc guns I think it's good stuff for the price.
