US Government destroy civilian 223 rifles

223 Rifles the US Government Destruction of- - The magic bullet refers to a successful product. Well the 556 bullet is a magic bullet to destroy civilian rifles. It looks the same as a 223 bullet in every way except it has a heaver powder charge. In a gun barrel there is a section called the throat if it were not in the gun, guns would eventually blow up. When the gun is fired the bullet has an unobstructed aria in the throat to move forward. This gives the bullet time to engrave in the riffling and continue forward. What they did was to chamber 556 guns with a longer throat. When that gun is fired there is for a mille second more case room so there is no pressure spike. On the other hand when a 556 bullet is fired in a 223 rifle the bullet only goes to the edge of the shorter throat and acts like an obstruction creating higher chamber pressure and the gun will in a short time blow up. The US Government agency SAAMI Sporting Arms and Ammunition Manufactures Institute could have fixed this long ago but had no intention to do so. Look on your gun barrel if it does not say 223 – 5.56, or 223 wild do not use 5.56 ammo in that gun.   If you want to know what is coming "American Handbook on Guns Ammo and Freedom" It is worth the investment it took me over 15 years to write it!
