At the 2023 SHOT Show in Las Vegas, Nevada, the .360 Buckhammer cartridge was introduced by Remington Arms.The Sporting Arms and Ammunition Manufacturers' Institute (SAAMI), the U.S. firearms and ammunition industry's technical standards-setting organization, announced the acceptance of the new cartridge and chamber standard on January 15, 2023.
In 2023, Remington introduced a new SAAMI-approved cartridge using the .30-30 Winchester as a parent case. The new cartridge, the .360 Buckhammer , or .360 BHMR for short, is based on a .30-30 Winchester case that has been blown out to get rid of the shoulder and necked up to accommodate .358-caliber bullets (the same bullets used in the .35 ...
Combined with the poorer ballistic coefficients of the lighter projectiles (.267 for the 125-grain Core-Lokt), this makes the .30 RAR a cartridge suited to ranges around 300 to 400 yards, although this can be extended with projectiles of higher ballistic coefficient (.341 for the Speer TNT 125 grain).

Factory ammunition usually are loaded with bullets weighing anywhere from 120 gr (7.8 g) to 140 gr (9.1 g). Bullets available to the reloader range from 85 gr (5.5 g) to 160 gr (10 g). The 120 gr (7.8 g) bullet has a sectional density of 0.246 which is similar to a 165 gr (10.7 g) .308 caliber (7.62 mm) bullet.

The 165 and 168-grain bullets with higher ballistic coefficient contribute to buck cross winds more efficiently and maintain downrange energy at expense of a more curved trajectory, while loaded with 180 to 220 grains, the .30-06 is adequate for hunting larger game such as elk, moose, and even brown bears.
The 7mm-08 with 139-140 grain loads does well against some 150-grain .308 Win. loads, providing good energy levels. One example is the Remington 7mm-08 140 PSP (1490 fpe at 300 yards) compared with the Remington 308 150 grain PSP (1344 fpe at 300 yards). [14] The 7mm-08 invites a ballistic comparison with the veteran, highly esteemed 7×57mm ...
Remington even re-branded the cartridge name itself for a fresh start with a 100-grain factory load as the 6mm Remington. While the 6mm Remington cartridge never took over the .24 caliber dual purpose market lead from .243 Winchester, it was successfully sustained in production for nearly six decades. [11]
