I guesstimate that I've shot 6 or 7 cases of their 9mm 124 grain ball over the past two years. The local distributor receives two or three shipments per year from Brazil so whatever we get is fairly current production. Burns cleaner, shoots softer, and is less loud than 124 grain Blazer Brass. Don't have chrono data for either load.
My range buddies have seen failures to ignite in Glocks with 4lb (or lighter) striker springs. My springs are OEM and have never had a failure to ignite so far.
That RSO isn't too bright.
The range I shoot at has pallet quantities of ammo, but the brand changes when they get a better deal. No problems with Magtech, Lawman, S&B, or Fiocchi in my 19, Dagger, or 92. That said, you'd have to check lot numbers. The ammo you shot could have been sitting around for two years, or it could have come off the boat last week.

Beware of my temper, and the dog that I've found...
I have noticed a bit of an issue over the last two range sessions with a lot purchased in the last year or so. Over two separate range sessions this week and last week I have had two failures to fire. Both times I've inspected the round and each one has had a typical primer strike without ignition. All rounds have been 9mm 115 FMJ which is my typical range ammo. This is a bit atypical as Magtech has been my go to for almost 6 years now.
I have also experienced hard primers in their 32 S&W Long ammo.
