7.62x40 WT Project
Project Goal
Develop an inherently accurate and low recoil cartridge in the immensely
popular .30 caliber that has more terminal effectiveness than the 5.56 while
utilizing as many standard AR platform 5.56/.223 components as possible.
Cartridge
Application
Designed for tactical/defense
applications as well as hunting for medium sized game such as deer and feral
hogs. The 7.62x40 WT (Wilson Tactical) 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 that’s
recoil sensitive.
Cartridge Specifics
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.
