I brought a box of Speer Lawman and CCI Blazer Brass(both 115g 9mm)to the range today...of the factory ammo I've tried, Lawman "seems" the hottest(next to S&B): I loaded one mag with the Lawman and one with Blazer Brass....I can't tell the difference. Both seem clean burning, accurate and nicely "hot": I don't reload, but the brass cases eject perfectly, while I used to have an occasional FTE with the Blazer aluminum. I will stock up on the Blazer Brass!
