Nosler has just introduced a new SAAMI-spec .338-caliber cartridge, the 33 Nosler, which is based on the 404 Jeffrey parent case. This efficient new cartridge rivals the velocity and energy of the proven .338 Lapua Magnum while using significantly less powder. AND, the Nosler 33 fits in a standard, long action receiver. Accordingly the 33 Nosler should be popular with extreme long range (ELR) shooters and big game hunters. The 33 Nosler fires .338-caliber bullets which are tough on big game and typically boast high Ballistic Coefficients and sectional densities. For long-range target work, Nosler will offer 33 Nosler match ammo with a high-BC 300gr bullet.

Notably, the 33 Nosler will fit in a standard-length Long Action. That’s a big deal because it means you can now achieve .338 LM performance in a rifle that is lighter and less costly to build. Nosler lists a 3.340″ COAL for the 33 Nosler. Compare that to 3.681″ for the .338 LM. Nosler will offer loaded ammunition as well as 33 Nosler brass.

The above chart was created by Nosler. It shows the 33 Nosler can push a 225gr AccuBond at 3025 fps and the 265gr AccuBond at 2775 fps. That’s 275 fps faster (with 20% more energy) than the .338 Winchester Magnum using the same length action. According to the chart, the 33 Nosler is also 25 fps faster than the .338 Lapua Magnum at the muzzle while burning 18% less powder. However, the numbers quoted by Nosler for the .338 LM are conservative.

The 33 Nosler® is SAAMI-standardized for consistent industry-wide brass and chamber dimensions. Nosler will be supporting this new cartridge with Nosler Brass, factory ammunition, and Nosler factory rifles. Expect 33 Nosler products to be available in early 2017.
