what is the difference between these two rounds. Have heard of the 7.62x40 wilson being fired in the 30x223 chambered rifles.

    Here is the case drawing for the 7.62x40 Wilson Tactical:

    http://wilsoncombat.com/new/762x40WT-cartridge-case.pdf

    Here is the description:

    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.

    The .30x223 is the .223 case necked up to accept the .30 caliber bullet without reducing the length of the case which remains 45mm.

    Best.
