Introducing the 7.62×40 WT (Wilson Tactical)

Despite coming out strongly for the .300 AAC BLK cartridge, Wilson Combat has developed their own 7.62x39mm-equivalent for the AR-15. The 7.62x40mm WT is a 5.56mm NATO cartridge necked up to .30 caliber. To convert an AR-15 to use the 7.62×40 WT a barrel change is (obviously) required and a special Wilson-modified version of Lancer’s L5 AWM polymer magazine.

The cartridge is designed with tactical/self-defense and hunting use with soft-point or hollow point projectiles. The company published this comparison with the 5.56mm NATO, 6.8mm SPC, 7.62x39mm & .300 BLK:

5.56 Nato (16” Barrel)
55 gr: 3150 FPS Muzzle Velocity and 1212 Foot Pounds of Energy
62 gr: 3000 FPS Muzzle Velocity and 1239 Foot Pounds of Energy
77 gr: 2750 FPS Muzzle Velocity and 1293 Foot Pounds of Energy

7.62×39 (16” Barrel)

123 gr: 2320 FPS Muzzle Velocity and 1470 Foot Pounds of Energy 


6.8 SPC (16” Barrel)

110 gr: 2550 FPS Muzzle Velocity and 1594 Foot Pounds of Energy 


300 BLACKOUT (16” Barrel)

125 gr: 2275 FPS Muzzle Velocity and 1436 Foot Pounds of Energy

Unlike the .300 BLK, the 7.62×40 WT has not been designed for suppressor use (ie. it is a supersonic cartridge). Remington will be manufacturing supersonic and subsonic BLK loads.

Wilson Combat 7.62×40 WT loaded with 110 gr. Sierra HP is on sale right now at a cost of $18 for 20 rounds at the Wilson Combat store.

    Wilson Got butthurt because he teamed up to make the 300 BLK and didnt want to go subsonic so he depearted and made his own in supersonic (so Ive heard)
    This Im sure will fade away because no one in there right mind would buy this set up instead of the 300 aac or a 6.8 or even the damn russian 7.62x39 because of his arrogant "Im better than everyone" pricing.
    I cant believe Wilson is still in biz with his rediculous pricing.

    Why all the hate? cant everyone just welcome someone's contribution to the shooting and hunting sport? So it isn't YOUR favorite... Why trash it for people who don't shoot anything but 5.56 and are looking for another caliber to shoot?
    Do you, Sir, have a financial interest in this cartridge? if so , then rant on YOUR website.
    Let people judge facts free of your spatterings of wisdom.

    Thank You.
