The M500 mechanical scale provides right or left-handed operation and a wealth of big-time features at an affordable price. 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 aluminum base even features a grain-to-gram conversion table to aid in calculations and recipe conversions. 505-grain capacity Accurate to within 0.1 grain Right- or left-handed operation Two-poise design Magnetic dampening Leveling foot Ambidextrous metal scale pan Grain-to-gram conversion chart
