As a rule. Military firearms are "over gased" so they will eject more reliably. Often results in harsh handling of empty cases.
If you DO decide to hand load. It's pretty well agreed that Reminton brass is the bottom of the barrel junk. Winchester brass is MUCH better, and typically the same price. Of course there are more expensive brands, but with a semi-auto you wont be using much, or any of the brass twice. Very few semi-auto's leave brass looking very good. Bad dents or scrape marks from magazine lips & bottom edges of load ramps, dents from extractors, ejectors, clips and magazines cutting into cases... The stuff usually isnt very pretty once you learn what to look for.
Reloading, or hand loading is primarily for bolt guns or single shots. There are exceptions of course!
Any AK I've seen will throw cases 15' and more, and nearly crush brass cases all the way in! 99% of military ammo in the world is steel cased, and not reloadable anyway. But the "over gasing" sure doesnt hurt semi-auto, or full auto reliability!
