Aluminum was 1140 fps with the 124 grain 9mm for a power factor of 142000.Just buy it. Good choice for factory quality ammo esp if you don't reload.
Anyone ever chrono aluminum cased ammo vs. brass ammo? Wonder if they are loaded a bit lighter for power factor issues.
I remember CCI used to have their 200gr Flying Ashtray JHP .45 rds loaded into their Blazer line.
Blazer aluminum is the only ammo that fails to eject from my CZ-Shadow. Bought a thousand rounds two years ago and I've had maybe one fail every three mags or so, bought a thousand rounds of Sellier and Bellot at the same time and not a single issue.
I haven't used it yet, but I plan on doing reliability testing with it in my CZ 75B and my new NP27.
Same problem I had with it, have not bought any since.
