Some members here say good things about them. Reloader Fred likes them and if he likes them, they are good enough for me. I bought some and loaded some of my 9MM plinker loads with them. They shoot as well as the same load where I have used Fed, CCI, and Win primers with the same bullet and powder charge. If any primer was more accurate, I couldn't shoot the difference. It would take a real good test to prove it one way or the other.
