I've been shooting PMC for 25+ yrs. Works as good or better than anything else out there. I'm currently using the 230gr Hardball, Awesome! I've ALWAYS loaded the Starfire line for protection, in all calibers. Hornady got too expensive! Fun Shootin'!
I haven't shot 45 in PMC but i have shot PMC in .223 and didn't have any issues. Not a single miss fire, no issues at all would buy it again with out hesitation.
PMC is good ammo. Not much more to say. Very reliable. I've heard a firearms trainer (who has witnessed millions of rounds fired) say that it's one of the few brands he has never seen blow up a pistol.
Like all previous posters, my experience with PMC ammo, though limited, has been positive. My 4516-1 liked it & begged for more. It didn't seem to be any dirtier or smokier than other brands I've used.
