Peterson Cartridge Unprimed Brass in .22-250 Remington with a large rifle primer (LRP) pocket (Peterson part no. 40087-R) gives varmint and predator hunters match-grade cases for one of the flattest-shooting cartridges available. Peterson holds this brass to a match-grade standard throughout small-batch production and quality control, the same process the company uses across its rifle brass line. That level of consistency matters in .22-250, a cartridge known for extreme velocities where uniform case capacity keeps pressures and accuracy predictable. Sold unprimed with a large rifle primer pocket, this brass is ready for a handloader’s own priming and charge selection.
