33 Nosler

The 33 Nosler is a 33 (.338") caliber, rebated-rim centerfire rifle cartridge designed by Nosler. Introduced in 2016 (production release 2017), the 33 Nosler is a SAAMIapproved and standardized cartridge. It is the fourth cartridge designed by Nosler.


The name 33 Nosler refers to the first two digits in the caliber (0.338") of the bullets that the cartridge fires and the name of the company which created it.

The 33 Nosler is Nosler's fourth cartridge following its predecessors the 26 Nosler which was released in 2014, the .28 Nosler which was released in 2015, and the .30 Noslerwhich was released in 2016. The 33 Nosler shares the same overall cartridge length (3.340") as the 26 Nosler, the 28 Nosler, and the .30 Nosler which allows it to be chambered in standard-length action firearms.

All four of Nosler's Cartridges the 26 Nosler.28 Nosler.30 Nosler, and the 33 Nosler are based on the same .404 Jeffery parent case. While the 26 and 28 Nosler share the same cartridge case dimensions, the 30 Nosler has a slightly shorter length to the shoulder dimension than the 26 and 28,[4] and the 33 Nosler has a shorter shoulder dimension yet than that of the 30 Nosler.[12]
