-Actually, the brass for 5.56 ammo is usually a tad longer... .
Mexican Match?
It is not just for full auto fire. The 5.56 chamber also allows the rifles to function longer in adverse conditions without jams. The M16A2, M16A4 and M4 Carbines are 3 round burst only. The M16, M16A1, M16A3, and M4A1 are full auto.i believe this was previously mentioned. The M16 and variants have generous chambers because the rifle is capable of full automatic fire
That myth has been busted time and time again. Those if us that reload can easily bust that myth. I have seen plenty of commercial .223 brass that is thicker than NATO 5.56 brass. And some commercial .223 brass will have less case capacity than NATO 5.56 brass.Looking at the actual case dimensions, there will be no discernible differences, even when looking at the SAAMI specifications, or for the dimensions of the reloading dies for the pair of cartridges. Yet, there are subtle differences. Initially, the first dimension that will be different is the wall thickness of the brass. As is the case with most military cartridges, the military NATO case will tend to have thicker walls, resulting in less case capacity, and a correlatively higher pressure given the same powder charge. If the exterior dimensions are identical, a thicker wall dimension must result in a smaller interior volume. That can and will pose a problem for those who reload their ammunition; I highly recommend segregating the cases and treating them differently.
You could load to a higher potential pressure within SAAMI specs for the 5.56
It would also be impossible because the 45 colt is much longer than an ACP round. Wont fit in the magazine, wouldn't feed and the Colt's rim wouldn't fit in the slide's breech face.It would be bad if people started loading .45 Colt into their 1911s.
It shouldn't be a secret by now that pressures are measured by 2 different methods
I get it, but it is like - univerally all of a sudden everyone deciding Amps means Volts, and everyone getting confused about why their breaker keeps tripping when they try to draw 120 Amps from a household outlet and having to watch it happen over and over in slow motion.It would also be impossible because the 45 colt is much longer than an ACP round. Wont fit in the magazine, wouldn't feed and the Colt's rim wouldn't fit in the slide's breech face.
Duh !!!
