What are you shooting?
I have some 550 bulk/economy box of federal 36gr I think hp. A 500 box of thunderbolt remington lead 40gr think it is. And I have about 5 50 ct boxes of aguila 40 gr copper super extra. And one box of aguila 38 gr copper hp. This last one shot pretty good in my new cz 455. The others didnt show any promising results.
