Overview

The RCBS Scale Check Weight Set - Deluxe (Model R98993) is a precision, passive calibration and verification kit designed to ensure the ongoing accuracy of both mechanical beam scales and electronic digital reloading scales. Over time, environmental factors such as dust, grit, and temperature shifts can affect scale sensors or balance pivots. This deluxe set allows Australian shooters and handloaders to verify their scales read true before dispensing live powder charges, which is a critical safety practice to prevent dangerous over-pressure conditions. Unlike standard sets that only total 60.5 grains, this Deluxe set offers a combined total weight of 510.5 grains, enabling verification across the scale's full functional range. The set includes a custom pair of forceps stored inside a dedicated plastic box; using these forceps is essential to prevent body oils and moisture from transferring to the weights and permanently altering their mass. Because this set consists of passive metal weights, it requires no electrical power, meaning it does not require 240V compatibility or SAA/RCM safety certifications for use in Australia.

Key Features

• Universal Scale Compatibility: Works reliably with all brands of mechanical (beam) and electronic digital powder scales.
• Full-Range Verification: Provides a 510.5-grain total capacity to test scales across their entire functional operating range rather than just low powder-charge weights.
• Forceps Included: Comes equipped with dedicated forceps to handle the precision weights, keeping them clean of performance-altering skin oils and dirt.
• Passive Operation: Completely mechanical design with zero power requirements, making it highly portable and maintenance-free.

Who is the Rcbs Scale Check Weight Set - Deluxe for?

• Precision handloaders — Verifies powder scale accuracy prior to charging cases with a maximum combined capacity of 510.5 grains, ensuring exact powder measurements down to a minimum resolution of 0.5 grains.
• Reloaders sorting finished components — Enables the verification of scale accuracy across a broad 510.5-grain range, making this reloading scale check weight set highly effective for sorting heavier, finished projectiles and brass cases.

Less suitable for: Handloaders who require calibration weights exceeding 510.5 grains, who should instead choose a heavy-capacity industrial calibration kit.
