I just picked up a Remington 700 Long Range in 300 Win Mag and am going to use it this deer hunting season. What would be the best factory load (brand and bullet grain) for whitetail deer? Most of my shots will be 150 yards and in, although I am set up to shoot out to 300 yards in the area that I will be hunting. I have read that some of the lighter grain bullets may blow up at shorter distance. Thanks in advance.
