Peterson 7mm Remington Magnum Long Brass Casings Box of 50rds 40071R

Peterson 40071R: 7mm Remington Magnum Long Brass Casings Box of 50rds

Peterson’s 7mm Rem Mag Long Brass is designed to headspace off the shoulder—not the belt—reducing case stretch and increasing brass life. Made in the USA with premium materials, these Peterson 40071R unprimed casings offer excellent consistency and durability for precision reloading. Box includes 50 casings, ideal for long-range shooting and hunting.

Peterson's Cases are the embodiment of uncompromising quality, crafted from premium materials and subjected to precise machining. The meticulous process begins with a coil of top-tier C260 brass, carefully selected for its excellence. This Peterson brass coil is transformed into "cups" through a series of steps that define the basis for superior casings.

These cups undergo a meticulous journey of refinement. Initially, they are drawn through a press three times, extending them into seamless tubes. Subsequently, they are trimmed to the desired length and thoroughly cleansed in preparation for the shaping process. The rear end of the tube is endowed with a designated "pocket" for housing the primer, while the extraction groove is expertly cut, ensuring flawless functionality.

With unwavering precision, the "mouth" of the casing is tapered to form the essential "neck," and the casing is once again trimmed to its exact specifications. A meticulously punched flash hole is incorporated in the primer pocket, and the mouth and neck undergo an induction annealing process to create the perfect grip for the projectile.

To conclude this rigorous journey, the cases receive a thorough cleansing, ensuring their impeccable state. After these meticulous steps, they are now primed and ready to be loaded, embodying Peterson's commitment to crafting exceptional casings for the most discerning firearm enthusiasts.
