"RCBS knows handloading. For over 60 years, R C B S has been producing high-quality gun reloading equipment that lets hand-loading enthusiasts get the most enjoyment from their hobby. The history of RCBS Reloading Equipment begins in a small back room as a hobby of Fred T. Huntington, who began making bullet swaging dies for manual reloading of cartridges intended for hunting the yellow-bellied marmot or ""Rock Chuck"", a western US varmint. These ""Rock Chuck Bullet Swages"" are history today, but the RCBS name lives on. The company today manfuactures high-quality gun loading tools and reloading supplies that every handloader needs, with custom tools for every step of the handloading process from start to finish. Hand-load fans will find a wealth of precision gun tools from RCBS, including trigger pull pressure gauges and scales for weighing out reloading powder, reloading presses, primer, trays, cleaning brushes, lubricant, priming tools, reloading dies and shell holders, bullet pullers and more."
