Nosler Introduces “World’s Most Powerful” 7mm: The .28 Nosler

28-Nosler-Banner-800

Nosler has announced what it calls the “most powerful commercial 7mm cartridge”: The .28 Nosler. Based on the same case as the .26 Nosler (itself based on the .404 Jeffery) , marketing literature for the round claims a performance of 160 grains at 3,300 feet per second from a 26″ barrel. From the press release:

NOSLER® UNVEILS WORLD’S MOST POWERFUL 7mm COMMERCIAL CARTRIDGE:

28-Nosler-Banner-800.jpg

Bend, Ore. – January 2, 2015 – One year ago, Nosler introduced their first namesake cartridge to the world. Since then, the 26 Nosler has achieved such renowned success that adding another member to the cartridge family became an obvious decision. Please welcome the 28 Nosler® as the most powerful 7mm cartridge commercially available today.

Ballistic enthusiasts are well aware of the benefits and advantages that 7mm (.284 caliber) bullets have, such as inherently high ballistic coefficients for long range accuracy and minimized wind drift.

The attributes listed above, in partnership with the Nosler bullets and velocities listed below will soon be available in Nosler’s Trophy Grade™ Ammunition. For those looking for the edge in power, velocity and long range performance in 7mm caliber, look no further.

  • Nosler® Trophy Grade™ Ammunition – 160gr AccuBond®
  • Nosler® Trophy Grade™ LR Ammunition – 175gr AccuBond® LR

The 28 Nosler® shares the same parent case as the 26 Nosler® as well as the C.O.A.L. of 3.340” allowing this cartridge to be operated in a standard length action for lighter weight and shorter bolt throw when compared to magnum length actions.

Of course, Nosler will be supporting this new cartridge with Nosler® Brass, Trophy Grade™ Ammunition and naturally, their full line of M48 rifles in 26” barrel configurations.

Nosler will initially offer two loads, a 160gr AccuBond and a 175gr AccuBond Long Range, in their Trophy Grade line of ammunition. The new cartridge also comes with its own website, and a full suite of promotional material.

    Unlike their other new calibers, this does seem to have a couple hundred FPS advantage vs. other 7mm magnums. However deplacing 7mm Rem Mag as the de-facto long-range magnum will take some work (given that you can buy plenty of factory ammo for it at &lt$1/rnd & there are plenty of fine rifles chambered in it it’s got a lot of advantages). The ballistics of good 180gr 7mm bullets look a lot like the lighter .338 Lapua loads…

    • Unsaid is that I wouldn’t really put too much emphasis on Nosler’s numbers, especially their BC figures.

      • Blake

        I couldn’t find a G1 or G7 BC number for these new 7mms on their site. Granted, I didn’t spend too much time digging, but they certainly seemed to publish a lot of data without providing the actual BC…

        • Sadler

          From Nosler’s own numbers: the 160 gr Accubond has a G1 of .531, and the 175 gr Accubond LR has a G1 of .672 and a G7 of .364.

          • If you look at Nosler’s website for the LR bullets, they’re giving i7 FFs in the range of .8-.7, which is ridiculous. There’s no way the bullets are that low drag.

          • MountainKelly

            Huge discussions on the LRH boards about noslers BC numbers

          • I think they’re confirmed to be massaged. There was a forum post somewhere where a guy went and shot them against their stated factory numbers, and the bullets dropped a lot more than the ballistic computer expected them too.

            No offense to Nosler, but I know what a bullet with an i7 FF of .75 looks like, and yours ain’t it.

          • MountainKelly

            Corrrct. The ballistics junkies over there did pretty exhaustive testing. If you’ve never been jump over there

          • Blake

            Thanks for checking that out. For purposes of comparison, Berger’s 180gr 7mm Match Hybrid Target has a G1 BC of .674 & a G7 BC of .345. I’ve read a few accounts of folks actually measuring Bergers based on real world performance & they’re really very close.

          • Here’re Nosler’s numbers for BC. Note that their BCs are G1, so you’ll need to convert them over to G7, then divide the sectional density by the BC to get i7 FF.

  • Sadler

    So it’s a 7mm RUM. They’re both based on a necked down .404 Jeffery, and both push a 160 gr bullet at 3300 ft/s.

    Real world velocities for the RUM are more like 3275 ft/s, we’ll have to wait and see what the Nosler can actually do. If I recall correctly, the 26 performed about 100 ft/s less than advertised.

  • Chris

    It appears to be almost identical (ballistic wise) to the 7mm STW. That is personally one of my all time favorite rounds, and what I have used for deer & elk hunting for the past 15 years. However, it never really caught on, and commercial ammo is reduced to three or four very pricey options (Nosler being 3 of the 4).

  • Jeff

    On the quiet day you can hear the throat being eroded…….

    • CrassyKnoll

      Hey! It’s those little flecks of rifling that make the bullet go faster doncha know?

  • MountainKelly

    If it’s not a throat murderer it’ll be great, I’ll wait and see. Until then 7STW is still king of the 7’s IMO

  • Riot

    That is one hell of a neck

  • Raoul O’Shaugnessy

    Does it come with a quiver to carry all the spare barrels?

    Here we go again with the Magnum craze. Its amazing no one has learned anything since the days of Jack O’Connor when he proved magnums are not needed, they are barrel burners and people generally do not shoot them as well either. At reasonable ranges guns like the .270, 280 Rem, and 7×57 are all that are needed for 95 per cent of all hunting. Most once a year hunters are not even skilled enough to be able to utilize a magnum caliber anyway as they can seldom hit much over 100 years in field positions. Even the .270 will kill game easily out to 300 yards and is not much behind the true velocity of most magnums like the 7mm Rem. magnum. The most underrated caliber ever made was the .280 Remington and is the wiser choice for most American hunting applications. With its 175 grain bullet it will shoot right through an elephant with no problem so why do you need a magnum. Truth is you do not.

      Amen brother; you’ve hit the nail right on the head! This industry has been run like the US car-industry for the past 4-5 decades, with it’s gas-guzzling engine technologies and it doesn’t like to see itself changing anytime soon to take on a slightly ‘greener’ approach! In case you haven’t noticed: Dinosaurs have been extinct long since and I know it might sound weird to you all, but the little, humble 6.5 Grendel is just about all you need to kill anything walking on this planet, with the right bullet, proper knowledge of animals anatomy and proper shot-placement skills!

    ??? WHO NDS. IT FOR WHAT??? For big varmints and small deer,243 Win. for bigger deer, 7mm/08or 280 Rem. ,for the rest, 338 Win. mag. with good bullets

    • Dean Seaman

      …or a scoped .30-06 for dam near everything. I share your opinion with a lot of new rounds I see these days.

  • Dean Seaman

    …and just like that, the 7mm Remington Magnum has become comparable to the .22 Long Rifle.
