You are going to have a horrendous wound, one that is very impressive to the eye. Especially if the shooter has not ever seen the effect of non milspec bullets on living tissue.
Also your going to significantly shorten the life of certain parts of the weapon. Air Force CATAM's using DoD approved Frangible ammo have reported throat errosion gauge failures at as early as 1500-2000rounds on M4's. I am not trying to say your ammo is frangible, just that it shares having a light weight bullet and high velocitys, and that is very hard on M4 barrels.

The Short barrel LW round is not designed to be fired from any 1/7 twist barrel longer than 14.5 inches. The design limit for the LW bullet from a 1/7 twist barrel is 3650fps. To fire the LW Short barrel 5.56 ammunition in any 1/7 twist barrel longer than 14.5 inches is contrary to product guidelines Le Mas Ltd. provides to its clients. To pressure test the Short barrel 5.56 LW ammunition in a non ported 1/7 twist barrel longer than 14.5 inches is stupid. To then publish such data is very stupid.

Very doubtful that any human being could survive a bare thoracic cavity impact from the Le Mas 7.62x51 LW bullet, period.
