338 ARC – 175 gr HP Match – Hornady Black (82271) – 200 Rounds

For shooters building a 338 ARC rifle, a consistent supersonic target load is the place to start zeroing, testing suppressors, and learning the cartridge. This listing is Hornady Black 338 ARC 175 grain HP Match ammo, MPN 82271, sold as a 200 round bulk case.

The 175 grain HP Match bullet is built for accuracy, with a hollow point design and a G1 ballistic coefficient of .385. Hornady rates this load at 2,075 fps with about 1,673 ft-lbs of muzzle energy, and designed it to run in direct impingement and gas piston rifles, carbines, and pistols, suppressed or unsuppressed. That makes it a strong choice for target work, steel, and getting to know the new cartridge.

The 338 ARC (Advanced Rifle Cartridge) is a newer Hornady cartridge built for the AR-15 platform and standardized by SAAMI in 2025. It fits a standard AR-15 lower with a 338 ARC barrel, a bolt and magazines made for the ARC case family. A common question is whether 338 ARC is interchangeable with 300 Blackout. It is not: the two use different cases and bullet diameters, so only fire this ammo in a firearm marked 338 ARC. The cartridge was designed around suppressor use, and Hornady offers it in both supersonic and subsonic loadings. Its .338 inch bullets range from lighter supersonic hunting loads to heavy subsonic projectiles, so one rifle can cover deer and hog hunting at moderate range as well as quiet suppressed shooting. Match bullets are made for paper and steel, so this is a target load rather than a hunting round. A 200 round case is a solid supply for range sessions.

Hornady Black 82271 is new production ammunition, not reloads, made in the USA. Each cartridge uses a brass case with a boxer primer and is non-corrosive, and the boxer primed brass is reloadable for handloaders. Buying by the case also keeps you on one production lot, so point of impact and velocity stay consistent from box to box. This case comes in factory packaging as 10 boxes of 20 rounds for a total of 200 rounds of 338 ARC 175 grain HP Match.
