The 7.62x40 WT was developed by Wilson Combat to a reliable .30 caliber solution for the AR platform with enhanced power, range and accuracy over other .30 caliber AR chamberings. It uses a standard bolt and a slightly modified, standard magazine.
Designed for tactical/defense applications as well as hunting for medium sized game such as deer and feral hogs. The 7.62x40 WT has very useful tactical applications with soft point and hollow point bullets providing reliable terminal performance on soft tissue while the Barnes TTSX will easily penetrate tough barriers. For hunting the 7.62x40 WT vastly out performs the 5.56 and is on par with the 6.8SPC at ranges out to 175-200 yards. The very mild recoil of the 7.62x40 WT also makes it ideal for female and younger shooters as well as anyone thats recoil sensitive.
The 7.62x40 WT is based on the inexpensive and readily available 5.56x45 NATO cartridge case. The 5.56 case is shortened to 1.560 and then re-sized (single operation) in a standard 7.62x40 WT sizing die which results in a formed 7.62x40 WT case with a finished overall case length of 1.565. The cartridge is designed for 110-150gr .308 diameter bullets loaded to supersonic velocities, but if chambered in a 1-8 twist barrel is also suitable for heavy bullet subsonic use also. An adjustable gas block is typically not required when switching from supersonic to subsonic. Loaded ammunition, components and modified magazines are available from Wilson Combat.
