All joking aside, I could honestly see a company accidently shipping fmj's instead of jhp's by mistake. That would SERIOUSLY tick people off. When you consider that a cheap box of fmj's for a 9mm run about 11 dollars for 50 rounds, and premium jhps in the same caliber run about a buck a round, that could be a BIG complaint :P.
I just remembered, this is the forum for the other hobby, so for those of you not familiar with the terms. . . fmj is full metal jacket, the cheap solid bullets for target practice, and jhp are the good but expensive self defense/hunting rounds that expand on impact. And just so everyone knows, incendiary rounds (the flaming ones) are not legal for civilians, you cant actually go out and buy those.
