Detailed Description

7.62x40 WT

The 7.62×40 WT is based on the inexpensive and readily available 5.56×45 Nato cartridge case. The 5.56 case is shortened to 1.560” and then re-sized (single operation) in a standard 7.62×40 WT sizing die which results in a formed 7.62×40 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. The 7.62×40 WT was designed around an optimal overall cartridge length of 2.250” which is a perfect fit in the new Lancer L5 AWM magazine and allows for proper case neck to bullet fit. Therefore the barrel throat was optimized for this overall length and the 7.62×40 WT does not suffer from the same inconsistent accuracy issues in the AR platform often seen with the 300 Whisper and 300 BLACKOUT. The 7.62×40 WT only requires one unique component, the barrel to build. All other standard AR platform 5.56 caliber components are compatible. The 7.62×40 WT will function reliably with standard unmodified Lancer L5 magazines if downloaded to 17 or 24 rounds or Wilson Combat has modified Lancer L5 AWM magazines with 18/19 or 28/29 round capacity available that function ultra reliable. Wilson Combat would like to express our gratitude to Kurt Buchert for all his early development work on this cartridge.
