I've got an old friend out of Laramie, Wyoming who is now 72 years old, who I think got an elk damn near every year since high school. Granted he went in on horses and had pack horses, plus a Canvas wall tent (die hard hunter), but he used a Remington 700 in a 270, and he used 130gr Federal Hi Shoks. He was mad when he couldn't get them at K-Mart anymore! A guy gave him a Ruger 77 in a 338 mag, and he told me the elk didn't seem to go down any faster, but he said "I can't believe the price of them at the sporting goods store, because he couldn't get the 338's at the Laramie K-Mart"! He used the 338 a few times but went back to the old 270 Remington 700.
