The 7.62x57mm UKM was designed by Michael Uekotter and certified by the Permanent International Commission for Firearms Testing in 2002. The parent case is based off a .338 Lapua Magnum by narrowing down the neck to fit a .7.82mm bullet on a large rifle casing. The ballistic performances for 5 grain type velocities are 3,468 ft/s (155 gr), 3,300 ft/s (168 gr), 3,240 ft/s (181 gr), 3,149 ft/s (185 gr), and 2,982 ft/s (220 gr).
While the 7.62x57mm UKM is no longer on the market, the American .300 Dakota is considered its twin. The .300 Dakota is based off the .404 Jeffery that was designed in 1909 as a rimless large rifle magnum cartridge. The .300 Dakota is a rebated rim which cuts down cost and allows users to change out barrels or custom fit receivers to use in different firearms.
The .300 Dakota is used for long range shooting, but like other bullets in its class the barrel needs to be replaced typically after 700-1000 rounds of wear on the barrel. To reduce wear on the barrel they should be cleaned after every 5 shots to help increase the lifespan.
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.
