6.5mm 140gr Spitzer Nosler Partition Bullets 50pcs
The Nosler Partition bullets in 6.5mm caliber and 140 grains have been the benchmark standard for precision hunters and ballistic enthusiasts since their introduction in 1948. Engineered with a fully copper alloy jacket that is completely tapered, these projectiles exhibit controlled and uniform expansion upon impact, with the jacket material peeling outward in a consistent manner. The innovative dual-core design features a front lead core that rapidly expands to create a wide wound channel, while the integral Nosler partition acts as a solid barrier, maintaining structural integrity and preventing core separation. This allows the rear core to retain over two-thirds of the bullets original mass, ensuring deep penetration through dense muscle and bone, which is critical for ethical and effective big game hunting.
This bullet construction delivers superior terminal ballistics by maximizing energy transfer and creating large permanent wound cavities, essential for quick incapacitation of game animals. The Nosler Partitions flat base design enhances stability during flight and improves accuracy, while the streamlined Spitzer tip optimizes the ballistic coefficient for flatter trajectories and reduced wind drift. These characteristics also facilitate consistent and reliable handloading, making the bullet a favorite among reloaders who demand precision and performance in their metallic and semimetallic cartridge assemblies.
