The RCBS MatchMaster Multi Case Reloading Block (Model R9499) is a premium, heavy-duty bench accessory designed to replace multiple calibre-specific plastic trays with a single, high-durability solution. Precision-machined from solid 6061-T6 billet aluminum, this mechanical, non-powered block provides an exceptionally stable platform for staging brass during critical stages such as case preparation, powder charging, and bullet seating. Weighing approximately 1.67 lbs (packaged weight), it remains firmly anchored to the bench and is built to withstand Australian workshop temperature extremes without warping or degrading.

Key Features

• DualFit Step Design: Features a proprietary stepped internal profile in each of the 50 wells. The lower, narrower section securely centers .223-class rims (.384-inch bolt face), while the upper, wider tier holds .308-class rims (.470-inch bolt face) to prevent case wobble.
• Precisioneered Pass-Through Holes: Small relief holes are machined into the bottom of each well to eliminate airlocks, ensuring cases sit perfectly flat while allowing stray powder flakes to fall through.
• Stackable and Non-Slip: Engineered with a machined top and bottom profile that allows multiple blocks to be stacked safely for storage, paired with integrated non-slip rubber feet to prevent sliding on smooth workbenches.
• No Power Required: As a 100% manual mechanical tool, it requires no 240V power or Australian SAA/RCM electrical certifications, making it ready for immediate bench use.

Who is the Rcbs Matchmaster Multi Case Reloading Block for?

• Precision rifle reloaders — processing .223 Remington and .308 Winchester family cartridges who require a highly stable, non-warping platform. This Rcbs Matchmaster Multi Case Reloading Block is machined from solid 6061-T6 billet aluminum and features a 0.47 inches hole diameter with a stepped design to eliminate case wobble during precision handloading.
• Benchrest handloaders — seeking a substantial, stationary alternative to lightweight plastic trays. With a hefty packaged weight of 1.67 lbs, this heavy aluminum reloading tray stays firmly in place on the bench, holding exactly 50 cartridges safely without the risk of tipping.

Less suitable for: high-volume progressive reloaders processing batches larger than the 50 cartridges capacity, or those loading small pistol calibres like 9mm and large belted magnums that fall outside the .384-inch to .470-inch bolt face threshold; for these applications, a dedicated high-capacity plastic tray or a calibre-specific large-bore reloading block is better suited.
