They are certainly not made for hunting and such either.
Though the rest of what you said is true, I disagree with your idea that the 5.56 x 45mm, or .223 is not a game-getter. It is, in fact, a fine, tho
under-rated, calibre for White-tail and Mule Deer, and Antelope. I wouldn't go any heavier with it, tho.
My Deer load for the .223 is topped out with a 64gr controlled expansion Horneday bullet, and a single round to the vitals will pass through 4/5ths of
a deer at ranges out to 250 yards, dropping them in their tracks. I haven't had to chase one up, yet!
Recovered bullets have always been intact and expanded to just under the size of a dime. These loads are available from Winchester.
On the AR-15/M-16(E2), I am the first person in the US Military Service to qualify Expert with this weapon, and was in the first unit of the Military
to train with it. We had the only M-16s in Vietnam when we shipped. We were also the ones that had the initial problems with the weapon, which was
traced to the fact that the ammunition we had was improperly loaded; causing an incomplete burn which left powder grains in the chamber neck causing
the following round to crimp and fail to eject. The manufacturer had used the same Ball Powder used in the 7.62, rather than the specified perf flake
powder, which burns much faster and cleaner. The only other problem we had was mechanical and had to do with the ROF at full auto.
That was somewhere around 1100 rpm as issued, which is rediculously fast and blows the accuracy due to bbl overheating. We solved this by installing
stiffer buffers which cut the ROF to about 850, and that helped a great deal.
On the .223, you are dealing with an very hi-velocity round. Out of the M-16, you are looking at 3800 fps at the muzzle. The trajectory of the
standard military load,
(55 gr FPBT), is tick-flat out to 300m and presents a drop of only 2" at 600m. The greatest knockdown power comes from hydrostatic shock. @ 300m the
round will totally dry and pulp an area within a diameter of 8" around the entry point in flesh.
I know from experience that a shot in the foot to a Human Being will completely shatter every bone all the way to the hip. IOW, a person hit with a
.223 is going to go down--period--and the likelyhood is that he will not get back up.
On a new AR, you are going to have to put between 200 and 250 rounds through the bbl before the rifle will "settle in". This is because the rifle
bbl is chromium steel rather than 4140 AS. Due to the hi-velocity, chromium steel has to be used to increase bbl life to something realistic, and it
takes awhile to smooth out the milling marks and burrs in the grooves. After that, the rifle becomes very dependabley accurate, and fully capable of
holding 5-round groups under the size of a quarter @ 300m consistently--and that with iron sights.
The first M-16s were a problem also due to the Ordinace depertment's idea that the action needed to be made to tighter tolerances. This led to other
jamming problems (extraction and injection) until the rifle was literally "shot loose". Before that great day, we had to keep the weapon
inordinately clean, a hard thig to do in the climate of Vietnam in I Corps when you are walking in ankle-deep Laterite all the time. Laterite is very
finely divided clay dust, which gets into everything and onto everythin it can't get into--which is not much. This is especially true of mechanical
things. For my own sake, I kept a condom over the muzzle attached with a rubber band, and wrapped the receiver with a single sheet of Sarran-wrap. The
gun will discharge with either or both of these items in place.
If any of you ever wanted to know another
use for a Condom--now you know.
For what it's worth, my scores on the Mod. "B" range were 248/250p the first time, and 250/250 the next time --2 years later. Yes, I got tagged for
the Rifle Team. My current arm of choice is a BWK-92; an AK-47 clone in .223, and it is every bit as hard a shooter and as accurate an arm as an
