I have one on my .338 Win. Mag and have not had a bit of trouble with it. I believe these are one of the most underated scopes out there.

Sorry, forgot to add that I'm getting 3/4"-1" three shot groups at 100 yards. It also survided air travel to Canada this past November with no problems. I have yet to have to rezero the scope, hope this helps!

I do not forsee any issues with that combo.

a friend of mine has had one on a .300 win mag for about 3 years. I asked him about a month ago how it was holding up. He said its been great so far w/ no shift in zero.

No problem at all.

7Rem mags are easy on most scopes..its when you cross the line and get into the 300's that a more rugged scope is required.

got one on a 300 Remington Ultra mag, and two on 7mm Rem mags. If it will hold up to a 300 RUM then it will hold up to a 7mm.
