At least it's SOUTH Korean! They made some good 30-06 ammo. Probably on US supplied equipment. I shot a lot of their .41 mag ammo. The brass was great. PMC was making ammo in the US for awhile.
I agree with others in saying it functioned well in M&P 9. Did notice it to be a little hotter than blazer brass and wwb. Last I bought was $11.50 per 50 about a yr. ago. zorro49
