If your building in preparation of an elk hunt, then yes a 7mm rem mag would be great, and fill a void between an 06' and a rum nicely. With that barrel, it will be just as heavy as your rum, maybe more. Do you have a specific weight goal in mind?Well my 30-06 already fills the roll of standard bolt face standard weight rifle. Its 9.5 lbs. My 300 RUM is supposed to be my elk rifle. It weighs 12 lbs now with a 6oz temporary scope. Ill be puting a nx8 on there eventually. I think the 7 mag fits better between those 2 than a 7-08. While perfectly adequate for deer Im starting to gather elk points again so hopefully in a couple years I can that 90% deer hunting down a bit. Thanks for all the thoughtful replies. I haven't changed my mind yet but I have gotten some good questions that have made me think. And kinda reinforced my position a bit.
Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1
Nightforce is such a solid combo of reticle, available elevation, glass that is good enough to shoot at the longest range you can dial. Nightforce has bullet proof construction that can handle the incidental horse rolling or some other rodeo action. -- bigngreen
The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
