The 223 Remington (5.56) is not legal to hunt big game in most states in the Union. The average body weight of a whitetail in Texas will not exceed perhaps 125 pounds. In my opinion (I always have one, I may not always be right but I am always sure) if the cartridge won't provide sure kills on an animal that size, how can it be expected to kill our enemies with heavy clothes on or even flak jackets. I was trained on the M1 Garand and later the M14. The 3006 and 308 are good one shot killers on most big game and on men also. They also have good penetration on barriers such as wood fences, brick veneer walls, etc and have good down range ballistics, being fairly accurate out 500 yds or more with close to 1000 ft lbs of energy at that range. I understand the rationale for the 5.56 being the weight and bulk of the ammo means a lot of ammo can be carried. If it takes 3 or 4 rounds to kill your enemy, would it not make more sense to carry less rounds but get surer kills with each round. I also understand that the 7.62 Nato requires a bigger, bulkier and heavier rifle and is still not controllable in auto fire. My proposal for the new cartridge would be: A new case, downsized from the 284 Win that would have the powder capacity of the 7x57 Mauser, and in .277(same as 270 Win) cal with a 130 grain boat tail spitzer bullet. The overall length of the 223 Rem is 2.26 inches, the overall length of the 284 Win is 2.80 inches. I estimate the length of the new cartridge would be somewhere around 2.5 inches. With a case capacity similar to the 7x57 it should develop about 2800 fps muzzle vel and because of the good ballistic coefficient and sectional density of the bullet with a battle zero at 200 yds it should shoot pretty flat to 400 yards and still maintain 1000 ft lbs of energy at that range. I used to shoot a 7x57 and the recoil is quite light, plenty light for a woman and would in a rifle of around 7.5 to 8 lbs be manageable in full automatic. However I do not believe full auto is desirable for your average infantryman. This cartridge would be ideal also for the SAW. The case would of course be fatter than the 223 but I believe the average soldier would have no trouble with an ammo load of two thirds the size now carried. I know many of you on this forum have recent combat experience(I have none) and many are hunters. What do youall think.
