Keahi: I have been so happy with the Leupold 3.5x10x40mm variable scope on my Elk Rifle - I have even used the "range finding" feature on it a time or two over the last 32+ years that I have had it on my favorite Elk Rifle (Remington 700 Classic in 7m/m Remington Magnum).
If I were to step up to a "more powerful" Elk Rifle it would be to the same caliber you shoot - 300 Winchester Magnum!
I have not had problems with my 7m/m Remington Magnum its just that more and more Grizzlies are inhabiting the places I Rifle Hunt Elk.
Hope you had a good season.
Hold into the wind
