Product Overview 300 wsm ammo
300 Winchester Short Magnum (also known as 300 WSM Ammo) is a .30 caliber rebated rim bottlenecked centerfire short magnum cartridge that was introduced in 2001 by Winchester.
Specifications 300 WSM Ammo
The overall cartridge length is 72.6 mm. The cartridge case length is 53.34 mm. The bullet diameter is .308 in (7.82 mm), which is common to all U.S. .30 caliber cartridges. The principle at work in the short magnum cartridge is the fitting of larger volumes of powder in closer proximity to the primer’s flash hole, resulting in more-uniform ignition. .300 WSM has a case capacity of 80 grains of H2O. The .30-06 Springfield holds 69 grains of H
2O; .308 Winchester holds 56 grains of H
2O; 30-30 Winchester holds 45 grains of H
2O. The .300 Winchester Magnum has a case capacity of 93.8 grains of H
2O. While providing ballistic performance nearly identical to that of the .300 Winchester Magnum, 300 WSM does this with about 14 grains less powder. The .300 WSM also head-spaces off of the case shoulder, versus the older .300 Winchester Magnum’s belted head space design.
The advantage to this round is ballistic performance nearly identical to the .300 Winchester Magnum in a lighter rifle with a shorter action burning 8 – 10% less gunpowder. A disadvantage of cartridge case designs with relatively large case head diameters lies in relatively high bolt thrust levels exerted on the locking mechanism of the employed firearm. Also, in small ring actions the larger chamber diameter removes more steel from the barrel tenon, making it weaker radially.
Nosler Trophy Grade ammunition is high quality, production-run ammunition manufactured to strict tolerances and inspected as it is hand-packaged. Trophy Grade features Nosler Custom brass and the dependable, high performing bullets you know and trust.This Trophy Grade ammunition is loaded with Nosler’s AccuBond bonded core bullet. Through a proprietary bonding process that eliminates voids in the bullet core, AccuBond marries Nosler’s traditional copper-alloy jacket with its special lead-alloy core. The result is a bullet that flies true, penetrates deep, won’t cause extensive barrel fouling, and will retain 60-70% of its weight. The white polymer tip helps protect against deformation while initiating expansion upon impact.
Nosler Trophy Grade ammunition combines Nosler bullets and Nosler brass to produce ammunition loaded with the absolute best in quality. Only Nosler bullets and Nosler brass are used, and each and every product is visually inspected by hand by a master craftsman to ensure it is within specification and the best possible quality. Nosler has been in business for years, and their commitment to quality translates into ammunition that you can depend on with every shot. This .300 WIN 180 grain Accubond is 180 grains of near perfection, bonded together with AccuBond. The loss of a single one of these relatively small bullets is a tragedy for long-time Nosler employees, but a happy ending all the same. Next time you order, pick up a box of Nosler Trophy Grade ammunition and make every shot count.
