I've been playing with it some and I'm getting slightly more pressure with the same weight charge as I got with the Nosler brass. The CCI BR4s are working better for me than the 450's did. I've got a great hunting load using Nosler 140gr BTs. 42gr of H4350 and a BTOL os 2.246 is giving me 2823fps average. It's shooting consistently right at .3" from my Savage 10/110 Predator.
