RCBS’ M500 mechanical scale provides right- or left-handed operation. Featuring a proven two-poise design that lets you weigh up to 505 grains with +/-0.1-grain accuracy, the M500 also offers RCBS’ magnetic damping system for fast readings, and maintenance-free movement. The tip-proof metal pan makes loading easier, and a rugged die cast metal base even features a grain-to-gram conversion table to aid in calculations and recipe conversions.
