I wrote Mueller Optics asking about this scope and it use on a double rifle here's what was said.

Subject: Question about scopes.
Your 2-7X32 Multi shot scope is listed for front loaders, shotguns and crossbows. Does that mean that it is unsuitable for a high powered rifle? Because of recoil?
I'd like to have a illuminated scope like this but I need it for a 9.3X74R similar to a .375 H&H.
Thank You"
"Hi Mike,
I would hesitate to mount it on a 375 unless there were some type of recoil reducing modifications done such as a muzzle break. The best scope suited for that rifle to handle the recoil would be our 3-10x44 Tac II.
Thanks
Mueller Optics"
So based on this I'd say that this scope isn't suitable for use on a drilling with a fair sized rifle tube.
I thought you guys may want to know.
