Best New Cartridge of 2011

This will make you wonder, why did I not think of that. Bill Wilson of Wilson Combat necked the .223 Remington up to .30 caliber and essentially created a lighter kicking, flatter shooting version of a .30-30 Winchester that works in an AR 15. The only modification needed is a new barrel. It’s called the 7.62 X 40 WT. Simply brilliant!

Wilson Combat's new and exciting 7.62 X 40 WT cartridge.

Next week the Gunwriter Assistant will attempt to take a wild hog with this cartridge. Look for more details on this cartridge in my September ammo column in Shooting Illustrated with a GunLocker review of the Wilson Combat Recon rifle in 7.62 x 40 WT in a later issue of that same magazine. My good buddy Charlie Sisk of Sisk Rifles is also preparing to build a rifle for this cartridge using a CZ 527 and a another great bolt-action project rifle for this new round would be Mossberg’s new MVP rifle.

    Looks just like the .300 whisper / .300 fireball / .300 blackout….

    Throw another design in the PILE of 30 caliber AR cartridges. What’s the next breaking news, a 380 that you can pocket carry?

  3. Auxin says:

    Aren’t 300 Blackout cases just necked-up .223/5.56 cases? Doesn’t it only require a barrel swap?Am I missing something?

  4. gunwriter says:

    They are similar but the Blackout has a shorter case with less capacity. It is probably a better sub-sonic only option. The 7.62 x 40 WT generates more velocity. Its splitting hairs but so is arguing over a 270 and a .30-06. Another thing is that the Blackout is touted as a sub and supersonic cartridge but you’ll find that in an AR you can not have one tuned to work both ways, you have to go one way or the other to get optimum results.

    According to the box of ammo in the photo, you can expect approximately 2400fps. from a 16″ AR using a 110 gr. bullet in the 7.62×40 WT. The black out on the other hand will give you 2315fps. from a 16″ AR using a 123gr. bullet. My personal opinion is the blackout is a better round due to the fact 220gr. subsonic ammo is out there for those who own suppressors. Another pro to the 300 AAC Blackout : ammo is READILY available and manufactured by Remington making it rather inexpensive. ($12.99 / 20 – 123gr. remington ammo) ($19.99 / 20 – 220gr. remington ammo)

    I did a little more research on this 7.62×40 WT, did anyone happen to catch the price on these uppers???? Just a tad more than I’m looking to spend…

  7. Bob M. says:

    I personally feel the .30 Remington AR is far superior to this round.

    • gunwriter says:

      No question about that – especially from a ballistics standpoint. However, the .30 Rem AR – a favorite of mine ( I have an AR and a bolt-gun in .30 Rem. AR) – was not introduced in 2011. And, brass is unattainable. The Blackout is a .300 Whisper which has been around for a long time. Remember, the title of the Post – Best New Cartridge of 2011 – I believe it has that hands down. This was never about a best cartridge ever or the best .30 cal AR 15 cartridge.

      As for the cost of the uppers, yeah, they’re expensive. So is everything Wilson Combat makes. Quality, believe it or not, does come at a price. I get the opportunity to shoot a lot of ARs and have yet found one to compare with a Wilson in quality or performance. Anyways, you can always buy just a barrel.
