Hi,
I don't know how much experience you have reloading generally, or for military semi-autos specifically. And I certainly do not intend to come across as an expert because I am not.
But, in addition to the very true comments you've already received (it ain't worth reloading for this caliber) and with which I agree, I will offer this.
Leaving out the fact that you can simply not save any money reloading, there are some safety issues relating to military rifles, especially autoloaders.
First, is "hard primers". There is a special grade of primer made for this. If you use regular primers there's an enhanced possibility of an AD upon chambering a round. Hard (that is to say "insensitive") primers do not eliminate this risk but they minimize it.
The second risk applies to all autoloaders (rifles and pistols) and not just military weapons. It is "squibs". I imagine you know that a squib means that the primer has fired but has not ignited, or has only partially ignited, the powder charge. The result is that the bullet fails to exit the barrel.
Sometimes, but not always, the bullet travels such a short distance that, even if you manually load the next round, it will not fully chamber, and the gun will not fire.
It has happened to me, with a Makarov pistol, that I had a squib but, somehow, there was enough of a detonation that the gun actually DID cycle and it DID chamber a new round, and this new round DID go into battery. It was only because the report sounded funny and because the recoil felt funny, that I did not pull the trigger again.
Had I done so, I would have blown up the gun, and possibly, my face. The bullet was about halfway down the barrel, stuck.
On that occasion I was using high end factory ammunition - not reloads. However, I would point out that, in my opinion, no hand loader is gonna have the equipment, the quality control systems, and the ORGANIZATION to produce ammunition that is reliable as factory ammo. I did not say more accurate, but more reliable.
Hence, I would be very disinclined to reload for any autoloader, and especially for a military type semi-auto. It is all too easy to get a squib, your finger twitch, or for whatever reason, continue shooting, and have an accident.
This is on top of the fact that brass is expensive and you NEVER recover all of it. Sometimes I think that the cases have gone into near earth orbit because no matter how hard I look I simply cannot find them. Brass is possibly the most expensive single component of a bullet and is the ONLY one that can be recycled.
All of the above is why you're best off shooting (and hand loading for) revolvers for fun and autoloaders for whatever other purpose you may have.
That's my story and I'm stickin' to it.
