Wilson Combat, known as a manufacturer of semi-custom 1911s, has introduced a new rifle cartridge in the form of the 7.62x40 Wilson Tactical (WT).

The 7.62x40 WT is a .30-caliber round designed for use with currently tooled 5.56x45 mm NATO/.223-caliber AR-platform rifles and requires only one modification—a new barrel. For hunters, the 7.62x40 WT is designed as an ideal hunting round for medium to large size game, and offers higher energy than the 7.62x39 mm with low recoil. For tactical users, the cartridge offers similar performance to the 6.8 SPC at ranges of 175-200 yards.

In addition to barrels and complete uppers chambered for the new cartridge, Wilson Combat is also offering handloading dies and tools, custom boxed ammunition and specially designed magazines fully supporting a transition to 7.62x40 WT.

Below is a chart provided by Wilson Combat indicating the ballistic performance of the round. For additional production information or to see the complete line of 7.62x40 WT products, please visit the Wilson Combat website.
