PETERSON 40045-R 7MM REM MAG 50/10

Peterson Cartridge 7mm Rem Mag brass is engineered for reloaders who demand consistency shot after shot. The 40045-R comes in a 50-round box with 10 pieces per bag, making it easy to organize and load in batches. Peterson's match-grade brass is built on tight manufacturing tolerances throughout every stage—from the initial draw to final quality inspection—so you spend less time sorting and more time at the range confident that your ammunition will perform predictably.

If you're building precision rifle loads for long-range hunting, competition shooting, or just want to maximize brass longevity and accuracy potential, Peterson's approach to case uniformity pays dividends downrange. Their small-batch production process prioritizes consistency over volume, which means less case-to-case variation in wall thickness, concentricity, and internal volume—all critical factors when you're chasing tight groups or load development reliability.

This is brass designed to be reloaded multiple times, so quality matters. Peterson cases hold their dimensions and integrity through repeated loadings, making them a solid choice for shooters who view reloading as both a precision craft and a way to extend the life of their components.

Frequently Asked Questions

What does match-grade brass mean?

Match-grade refers to Peterson's manufacturing standard that emphasizes tight tolerances and consistency throughout the entire production process. This results in cases with minimal variation in wall thickness, internal volume, and concentricity—factors that directly support accuracy and load development reliability.

How many times can I reload Peterson brass?

Peterson brass is designed for multiple reloading cycles. The exact number depends on your load intensity, case care, and inspection practices, but quality match-grade brass like this typically outlasts lower-tolerance cases by a significant margin.

Is this brass suitable for long-range hunting and competition?

Yes. The consistent case quality and tight tolerances Peterson maintains make this brass well-suited for precision shooting applications where shot-to-shot consistency is critical, whether you're hunting at distance or competing on the range.

What's included in a box?

You receive 50 pieces of 7mm Rem Mag brass packaged as 10 rounds per bag, making it convenient to organize and load in batches.
