Peterson 40003R .300 Weatherby Magnum Casings Box of 50

The Peterson .300 Weatherby Magnum Brass Casings 40003R are premium, unprimed brass cases designed for precision reloading. Made in the USA by Peterson Cartridge, they offer excellent consistency, durability, and sub-MOA potential. Ideal for big game hunters and long-range shooters, these Peterson 40003R casings are compatible with large rifle primers and come packaged in a durable plastic box.

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.
