Well, I live in colorado, north part of the state. I used to be concerned that a 270 wasnt enough, so I got rid of it for a 30-06. That wasnt enough so I got a 7mm mag, then bought a 45-70. To that point I hadnt even shot an elk yet and was wirried I didnt have enough gun, all the guys at work were shooting 338's and they work like a charm, alot of missing. The, I met a fellow that hunts with a 243. He shoots 100 grain bullets. Got a 4X5 elk, bot huge, but over 600 on the hoof at about 150 yards. He put it in the heart. The bull dropped within 40 yards. Elk hunting is a good excuse to get a new rifle. I now use a 7mm WSM with a Zeiss scope on it for everything. Shoot what your comfortable, but by all means tell your wife that your gun is inadequate to help the process along!
