I bought rifles every other year to find one I liked and worked well on elk. After 30-06, a couple 300 win mags, 308 winchester, I last tried a Remington 700 mountain rifle in 270 win. Its a pleasure to carry, shoots well and allows me to practice a lot without penalizing recoil. It became my main rifle but I fill in with others depending on short walks, timber hunting etc. I shot both my big bulls (and a lot of others) with it and it does the job well. I use 140-150 grain sierra BT for it.
I used 180 grain partitions in a 300 win mag on one bull about 150 yards. Hit him in the breadbasket 4 times before he went down. So I felt some of the premium bullets are overrated if you aren't hitting bone.
Being a rifle competitor, range officer, manager, instructor, I always tell people when they ask for caliber recommendations, to use the biggest caliber you are most comfortable shooting with.
I do think the 7mm remington magnum would be one of the best rounds but never used one.
