.338 Remington Ultra Mag Brass Cases 100 Count
Remington Brass Case Caliber .338 Remington Ultra Magnum.
Bulk pack containing 100 units per box, ideal for precision reloaders and ballistic enthusiasts.
Each Remington case is meticulously engineered from a premium brass alloy, specifically formulated to deliver consistent internal volume and exceptional tensile strength, minimizing case stretching and brittleness during repeated firing cycles.
The neck annealing process is precisely controlled to facilitate optimal case neck expansion and contraction, significantly extending the lifespan of each case through multiple reloads while maintaining reliable bullet seating and neck tension.
Remington maintains rigorous manufacturing tolerances, ensuring each metallic component adheres closely to exacting dimensional standards for superior uniformity and performance in high-pressure rifle cartridges.
All cases are produced within SAAMI (Sporting Arms and Ammunition Manufacturers Institute) specifications, incorporating advanced heat treatment protocols and proprietary design enhancements to maximize structural integrity and durability under extreme ballistic stresses.
These are new, unfired brass cases, delivered without primers installed, allowing reloaders full control over primer selection and seating depth for tailored ballistic performance.
Prior to loading, it is essential to trim and chamfer the case mouths to precise dimensions to ensure consistent bullet alignment and prevent jacket damage during seating.
Due to manufacturing tolerances and transportation handling, case mouths may exhibit slight deviations from perfect roundness.
To guarantee optimal bullet seating and chamber fit, cases should be resized using an appropriate expanding die, which will simultaneously round and slightly flare the case mouth, facilitating smooth projectile insertion and preventing bullet deformation.
Deburring and removal of any residual flash or burrs at the case mouth is recommended before the reloading process to maintain consistent chamber pressures and accuracy.
Additional Notes:
New brass cases may display discoloration or spotting on the neck and body surfaces. This is a normal result of the annealing process performed by the manufacturer, involving rapid heating to a precise temperature followed by controlled quenching.
This thermal treatment imparts the necessary hardness to securely hold the projectile while providing the flexibility required for case expansion and contraction during firing and subsequent resizing operations.
The visible staining is merely a residual effect of this heat treatment and does not affect the structural integrity or performance of the brass cases.
