Brown Bear, PPU, Magtech, etc. are brand names. They tend to be less expensive because of where they're made. Brown Bear is Russian, as I recall. The ruble is virtually worthless compared to a U.S. dollar. 1 ruble is worth .0147091 USD. However, less expensive ammo won't hurt a standard AR. An AR is not a target rifle. Don't think I'd want to use steel cases or steel jackets out of an HBAR or any gussied up rifle though. Steel on steel might wear a bit quicker.
"...cheap ammo for Ar-15's has a steel core..." That's the bullet, not the case.
"...thought steel cases couldn't be "worked" like brass..." They can't and usually are Berdan primed. Steel cases are mild steel. Mild steel will not resize to factory dimensions regardless of anything you try to do. Brass is elastic and will resize to factory dimensions.
