$643.74
The Peterson Cartridge 300 RUM 250-count bulk pack gives serious long-range shooters and handloaders the component volume they need without constant restocking. Peterson brass is known for consistent quality and tight tolerances—critical traits when you're chasing precision at distance or building ammunition for demanding applications. Whether you're assembling match rounds for the range, hunting loads for magnum rifles, or testing loads during a development session, having 250 cases on hand means fewer supply interruptions and more time behind the gun.
Bulk purchasing also makes economic sense for reloaders who shoot frequently or work through multiple load development cycles. Peterson's reputation for uniform case walls and reliable primer pockets translates to less sorting and prep work, so you can focus on the actual reloading process and fine-tuning your loads for accuracy.
The 300 RUM (Remington Ultra Magnum) remains a popular choice for long-range hunting and competitive shooting, and having quality brass in volume means you can develop proven loads and shoot them with confidence. This bulk pack is designed for the dedicated handloader who understands the importance of component consistency.
