I have a 300 win that I am taking on my first Elk hunt this December. It is a late cow Elk hunt. I have never shot an Elk before and need some help with bullet selection. I do not know how close the shots will be but I am prepared to shoot out to 700 yards. I have 3 different loads I am considering. They all shoot around the 1 inch to 1 1/4 inch at 300 yards. The first one is a 180 Accubond traveling out of the muzzle at 3122FPS. The second bullet is the 200 Accubond leaving the muzzle at 2960FPS. The third bullet is a 220 Matchking leaving the muzzle at 2750fps. I am kinda leaning twords the 200 Accubond but then I look at the bc of the big Matchking. Any thoughts?
