RE: New Rifle
I use a 338 wm for all my big game hunting anymore. I got it for elk, but found that with 200 gr bullets it does a fine tight shooting group to 350 for antelope. I do not shoot beyond that 300 to 350 anyway. The 250 gr is what I use for elk, and settles them down.
And before anyone says it, the 338 in the chest of a antelope sets them right down, with no more than average damage to the meat. It slips right through doing its job. Doesn'lt matter what you use, you hit the shoulder bone, the animal is toast in the front quarters.
If I were looking for something else, it would be a 30-06, 150 gr for the antelope, 200 gr for the elk. The 150 flat shooting and more than enough, the 200 has the beef for an elk.
