The well-known US ammunition manufacturer Nosler has added a new entry to their branded cartridge family: the 30 Nosler, that joins up with the existing 26 and 28 Nosler cartridges, all of them sharing the same basic case.
The 30 Nosler takes all the best attributes of currently available 30 magnums and combines them in one cartridge. The 30 Nosler easily meets the velocity of the 300 Weatherby, headspaces on the shoulder like a 300 RUM, has an efficient powder column like the 300 WSM and fits in the same standard length action of a 300 Winchester Magnum.
The 30 Nosler is a SAAMI standardized cartridge making for consistent brass and chamber dimensions industry wide. Nosler will be supporting this new cartridge with Nosler Brass, Trophy Grade Ammunition and naturally, the full line of M48 rifles in 26†barrel configurations.
The .30 Nosler is a 30-caliber (.308 in; 7.62 mm), rebated-rim centerfire rifle cartridge designed by Nosler. Introduced in 2016, the .30 Nosler is a SAAMI approved and standardized cartridge. It is the third cartridge designed by Nosler.
The name .30 Nosler refers to the first two digits in the caliber (0.308 in; 7.62 mm) of the bullets that the cartridge fires and the name of the company which created it.
This is Nosler's third cartridge following its predecessors the .26 Nosler which was released in 2014 and the .28 Nosler which was released in 2015. The .30 Nosler shares the same overall cartridge length 84.8 mm (3.340 in) as the .26 Nosler and the .28 Nosler which allows it to be chambered in standard-length action firearms.
Four of Nosler's Cartridges, the .26 Nosler, .28 Nosler, .30 Nosler, and .33 Nosler, are based on the same .300 Remington Ultra Magnum parent case. While the .26 Nosler and the .28 Nosler share the same cartridge case dimensions, the .30 Nosler has a slightly shorter length to the shoulder dimension than the .26 Nosler and the .28 Nosler, and the .33 Nosler has a shorter shoulder dimension yet than that of the .30 Nosler. The .30 Nosler was released in January 2016. Later in October 2016, Nosler continued to add to the cartridge family by releasing the .33 Nosler, and in January 2017 they introduced the .22 Nosler.
The 300 PRC is an intelligently crafted 21st century magnum cartridge specifically designed to take advantage of long, heavy for caliber bullets capable of delivering the highest levels of accuracy and aerodynamic performance.
Based on the 375 Ruger cartridge case, the 300 PRC is non-belted and uses a standard .532†magnum bolt face and headspaces off the 30 degree shoulder. This results in better chamber alignment than standard belted magnum cartridges and allows for improved stacking and feeding from fixed magazines.
The 300 PRC cartridge and chamber were designed concurrently combining to provide excellent alignment and highly tuned performance. The cartridge case is designed to use common, temperature stable, magnum speed rifle powders producing extremely consistent velocity and increased barrel life compared to currently available magnum cartridges.
