Does anyone know what S&B uses for their metal jacketing? I can't find what they use anywhere (including their site). It's not copper and looks like brass to me. It is also not steel as it does not react to magnets.
All the S&B I've seen locally and bought has been brass cased (I think the box even mentioned it) and has worked reliably. The .223 hasn't been the most accurate, but that's more a problem with it being too light for my 556.
