I've shot quite a lot of the South African PMP (new manufacture, brass case, reloadable, commercial, packed in boxes with a gazelle on the front). I've been happy with it (no misfires or other problems that I recall). I think I paid about $115 plus shipping for the last two cases I ordered, but I haven't seen it this low for awhile.
I've been thinking of getting some Korean surplus ammo that is available very cheap - but is said to have tarnished brass, beat up boxes, etc. Anyone tried this?
A friend has also suggested that I try the Wolf steel cased Russian ammo. I think I've read reports of lacquer from the ammo building up in the gun, and of the steel cases being hard on AR extractors (I'd be shooting this ammo in ARs and a Mini-14), so I'm reluctant to try this - especially when, up to now, I've been able to buy brass-cased ammo for just a little more.
I think I'll probably stick with the South African for reloading and any circumstance in which I really want reliability and consistency. But a case or two of some really cheap ammo would be fun to plink with if it won't damage the guns and works reasonably well. I'll be watching this string with interest.
