Nosler Partition Bullets .270 cal .277" 140 gr SPT 50/ct

The Nosler Partition Bullets .270 cal .277" 140 gr SPT is a premium reloading component engineered for precision rifle hunters and competitive shooters who demand reliable, consistent bullet performance. Available in 50-round boxes, these .270 caliber projectiles represent seven decades of Nosler's ballistic innovation and are ideal for hunters pursuing medium to large game at extended ranges where controlled expansion and deep penetration are critical.

The Partition design features a fully tapered jacket that initiates immediate expansion at the bullet's nose, while a thickened steel partition wall manages the expansion rate and retains a substantial weight-carrying base core for deep, reliable penetration. This dual-core construction—the defining innovation that made Partition bullets legendary—ensures controlled mushrooming on impact, maximizing energy transfer to vital zones while minimizing pass-through fragmentation. At 140 grains, this weight class delivers an optimal balance of velocity and retained energy in standard .270 Winchester and .270 WSM platforms, with stable flight characteristics across typical hunting distances.

Handloaders using modern .270 Winchester cartridges will find these bullets perform exceptionally well with powders such as IMR 4350, H4831, and similar medium-burn-rate propellants. The 140-grain .277" projectile maintains excellent BC for wind-bucking performance and groups consistently at 200+ yards when loaded to proper pressures and seated in quality brass. Serious reloaders, long-range hunters, and target shooters who value time-tested expansion technology and proven field results will recognize the Partition's reputation for delivering clean kills and reliable performance across variable hunting conditions.
