.223 rem and NATO 5.56x45 are the same except for bullet weight and construction, not length. Standard .223 is 55 grain, which is the round the AR-15
was developed for by Stoner, and current NATO 5.45x45 is the SS-109, which has a 62 gr. projectile, and requires a different rifling twist on account
of the added weight. The problem is that they've over-stabilized the bullet, trying to make something out of it which it was never designed for.
Blame the USMC - they started that crap. The "added wear and tear" resulted from the higher weight bullet skipping the rifling and wearing it out
quicker, not from a dimensional difference.
I've never had a feed problem with tracer or AP in either M-16's or AK's. The green tracers for AK's are a little disconcerting after getting used
to red US tracers, but they can help point out which hole you need to be shooting into - just check to see where the green tracers are coming from.
The tracers do tend to foul more, requiring more cleaning, but that's not a dimension problem. Tracer bullets
tend to be longer to accommodate
the tracer composition, but they are seated in the case to the same depth, giving the same overall length.
Ammo load is an individual thing - a standard US 5.56 loadout is 210 rounds, but SpecOps carry more, and the Soviet Spetnaz in Afghanistan regularly
carried 600 round loadouts for their AK's. Regular Soviet troopers carried only 125 rounds, because they were only issued 5 30-round magazines per
weapon, and Russian practice is to only load 25 rounds into each 30 round mag.. Those who could scrounge more magazines carried more ammo.
The "teflon coating" you are referring to is for pistol caliber bullets, not rifle. ANY center-fire rifle round will penetrate a IIa ballistic vest.
ANY full metal jacketed round will, too - teflon or no. My vest has a titanium trauma plate that is supposed to be able to stop a 7.62x 51 NATO round,
but I hope to never test that theory out. If it misses the trauma plate, it'll go through like a hot knife in butter - including through ME. You have
to upgrade to level IIIa in order to start defeating those types of rounds, and IIIa isn't standard issue for beat cops, because it's so bulky. IIIa
is what you see on SWAT teams. Steel core AP (rather than standard lead core ball) will punch through that, too.
