I bought my steel balls conveniently collect these neodymium from the backstop. Once through threats and even hanging 50 - off 60 pieces 8mm steel ball. Works of course equally well with 12mm steel, are in this case only the less dranhängen can. Alternatively, I clip the carabiner thanks in part to the belt loop and did so ever 50 shot 8mm Muni handy when Zwilleschießen. From my thumbs up and strong buy recommendation.
