Until today I had avoided the AR platform. But today I bought a S&W M&P15 flat top. I have heard that AR's in general can be picky about ammo. Some don't like the Wolf because of the lacquered case, some don't like handloads. I was wondering about the Silver Bear ammo, even though it is a steel case, it is nickel plated instead of the lacquer coating. Anyone have comments on what to feed the new toy?
