Question is: has anyone out there used this scope on a heavy recoil rifle and will it hold up to a real thumping that this rifle would subject it to?
I have 3x9 Nikon Monarchs on my Ruger No. 1 45-70 Gov't and on my Savage 7mm Rem Mag. While not the the same scope model as yours, I've not had any issues with them and both hold zero very well. The Ruger is pretty light weight and can give you a good thump but the scope has never lost zero.
I don't think you'll experience any issues with yours either.
