I use the four brands commonly found in the US. Federal, CCI, Remington and Winchester. I usually let the load and rifle tell me which one they like. For example, my son and I have four different WBY MK5 300WBY rifles. One I load with 180 grn Nosler BT/AB and IMR4350. This likes Remington 9 1/2 L R (NOT Mag). One I load 180 grn Barnes TSX with IMR7828. This one likes CCI200 (NOT MAG). Two I load with 200 grn Nosler AB/PT with RL22. These two like Fed215 (Magnum). These work for me.
