I usually use Win white box or S&B for practice but figured I'd try the new Blazer Brass 9mm FMJ and I'm glad I did. My groups shrunk significantly into one big hole at 50 ft. It was like shooting a laser beam. I don't know if my pistol just likes this load or if Blazers loading equipment is new and is making tighter tolerance ammo than the other guys but whatever they're doing it works for me. There is more flash with this ammo but that's not a problem for me. No more WW or S&B for me as long as Blazer doesn't raise its price.
