The RCBS M500 Mechanical Scale delivers precise powder measurements for handloaders who demand consistent accuracy without electronic complexity. This beam-style scale handles charges up to 505 grains with reliable mechanical operation that never requires batteries or calibration drift concerns.
What Makes This Different
Unlike digital scales that can drift or fail due to electronic interference, the M500 uses a proven magnetic damping system for quick, stable readings. The self-aligning agate bearings provide smooth operation and long-term accuracy maintenance. The hardened steel knife edges resist wear while maintaining precise balance points that remain consistent across thousands of weighing cycles.
Key Features
- 505-grain maximum capacity handles all standard rifle and pistol powder charges
- Magnetic damping system eliminates oscillation for faster readings
- Self-aligning agate bearings ensure smooth, consistent operation
- Hardened steel knife edges resist wear and maintain accuracy
- Large, easy-read graduated beam with 0.1-grain increments
- Sturdy die-cast base provides stable weighing platform
- Includes 505-grain certified check weight for verification
Competitive shooters and precision handloaders rely on mechanical scales for match-grade consistency. The M500 maintains accuracy across temperature variations and electromagnetic interference that can affect digital units. Whether measuring precise charges for long-range rifle cartridges or consistent pistol loads, this scale delivers the repeatability serious reloaders demand.
