Interesting Caliber Selections

A bolt action, multi-barreled, precision rifle, with a ten-round magazine. Very cool.

New Marine Corps sniper rifle is officially operational

The Marine Corps has officially hit full operational capability on its new sniper rifle a year ahead of schedule.

The Corps chose the Mk22 Mod 0 Advanced Sniper Rifle, manufactured by Barrett Firearms, a company widely known for their groundbreaking work in developing the .50 caliber sniper rifle, as a changeable, multi-barrel rifle to replace two existing long rifles and give shooters three caliber options within their main shooting platform.

Those caliber options include the standard 7.62mm, the .300 Norma Magnum and .338 Norma Magnum. The caliber diversity allows shooters to select a munition for specific missions that might require more distance or more penetrating power. The rifle uses a 10-round magazine.

The .338 Norma Magnum cartridge pushes a 300-grain Sierra Matchking out the barrel at 2,700 fps.

The .300 Norma Magnum cartridge achieves a blistering 3,000 fps with a 220-grain bullet.

Those are some interesting calibers for a 15.2-pound rifle. They must deliver some serious kick.

I wonder how long it will be before someone brings one to Boomershoot.

  1. In light of the information coming to light about Russia’s new intermediate-range ballistic missile, Oreshnik, they need more than a new rifle. They need an entirely new doctrine and force structure, logistical design, and strategic vision.

    Trump has his work cut out for him, but the best time to effect change is when it becomes obvious the old ways are not working.

    • Current doctrine seems to be to hold islands against the Chinese until they starve to death like the Japanese in WW2.

  2. WTF??? The Marines just ended their sniper program. I’m sure Hegseth will be bring it back. But damn. Make up our minds already.
    Ya, the Army adopted the M22 several years. Really cool.
    If someone is looking for a good switch barrel that won’t cost an arm and a leg. Check out the Seekins Havak HIT. It won’t shoot the big-boys like the Lapua’s cartridges. But you can switch barrels inside of 2 minutes with below MOA accuracy. And bolt heads also.
    Really sweet rigs.

  3. I looked for a price; some Google hits show numbers in the $15k range. Nice rifle, but that sure is a high price.

    No Lapua for this rifle, instead Norma Magnum .338. Made me look that up. Interesting.

  4. I’m wondering where the latest crop of ELD projectiles lands in all this; Hornady, among others, has a selection that reportedly works well – and one of which is a .30 caliber, 220 grain offering – I’d expect to see something like them show up in the 300 Norma loadings.

    This will be interesting to watch.
