The RCBS M500 Mechanical Scale (RCBS part no. 98915) is a multi-caliber beam scale built for right- or left-handed operation on any reloading bench. It uses a proven two-poise design that weighs up to 505 grains with plus-or-minus 0.1-grain accuracy, and RCBS’s magnetic damping system settles the beam quickly for fast, maintenance-free readings. A tip-proof metal pan simplifies loading powder or bullets onto the scale, and the rugged die-cast metal base even includes a grain-to-gram conversion table printed right on it for quick recipe conversions.
