I picked up some Blazer Brass 9 mm ammo (brass case) from Natchez at a good price. Today I shot about 100 rounds and I noticed significant muzzle flash with each round. I'm talking about enough flash to make me flinch after each shot. Wondering if anyone else has noticed this with this ammo? I've got a 1000 rounds of this to go through, and I'm not looking forward to it.
