I use Blaser Brass when I shoot 9mm for IDPA, and am usually first or second out of 20+ shooters. I even shot my .40 a few weeks ago for IDPA, using BB, took 5th out of 27th, having never used this pistol/ammo for IDPA before, I think that assures its quality.
Ususally I shoot my G20 10mm and my own handloads though.
Blaser brass is great ammo, I like it better than WWB.
I was able to find 10k rounds of it earlier this year at a walamrt in lexington KY, and bought every box of it. Took it home, sold half of it, and the other half is in safe #2.
