Purchased two boxes at Wally World. The 9mm is good and never had any issues with the 9. .40 failure to feed virtually every round through an S&W M&P Pro 5" C.O.R.E. Had to empty half the 15 round mag's and maybe they'd go bang. Ran 300 round of the 9mm through a Springfield XDM 4.5" with no issues.

I'll continue to use the 9mm but two boxes of .40 and I'm done. Blazer Brass, American Eagle or . . . anything but Perfecta in .40.
