Pet load for deer: 150-grain Sierra SP, either flat-base or boat-tail. My max load is 52.5 grains of 4064, but I advise starting a tad below that. I've had excellent results with the Sierra 180-grain SPBT for accuracy; 54.0 grains of H414 is the book's max load.
It never has seemed to matter whether I used Remington or Winchester primers.
