i've only owned 3 elk killin rifles. a tang ruger in 270win from 1973 to 1996. didn't reload so shot factory corelokts, which worked well on sheep, moose, a couple black bears, and a few elk. i travel to either colorado, montana, or new mexico every year for elk and in 1996 i switched to a ruger mk2 in 30-06, again using factory ammo except i switched to fed premium stuff loaded with 180 gr partitions. last year and two or three prior years i used a win m70 ew in 308win for my annual elk hunt. wouldn't you know it, the 308 killed just as well as the 30-06. i've given most of my rifles to grandkids now, so only have a 308 and an 06. haven't decided which one i'll use this year. for you guys that are elk huntin this fall, i hope you have a great time.
