I promised y'all a review of Freedom Munitions once I'd shot some, so just for fun, I loaded up 2 extended magazines and took them to the range this afternoon. One had 30 rounds of store-bought 9mm Blazer, the other had 30 round of 9mm Blaster from Freedom Munitions. Both were 115 grain FMJ.
I did not detect any difference in performance or operation between the store-bought ammo and the commercially reloaded ammo. It was indistinguishable to me.
If anything, it was the magazines which gave me trouble with several Failures To Feed. Ironically, the mag with the store-bought stuff had more FTFs (3) than the one with the reloaded ammo (1), so I'm chalking that up to "Extended magazines sometimes do that" instead of blaming it on the ammo.
For my next test, I'm going to shoot 100 rounds (or more) of the reloaded Blaster and see if there are any malfunctions that I can attribute to the cartridges themselves. I don't think I'll find any, but 10% of my volume should be a statistically significant sample.
