Generally, no. With a .577 or .600, maybe, but not otherwise. A properly built double just doesn't have the recoil of a comparable magazine rifle. It just isn't an issue.

A double rifle is a basic tool that should be used pretty much the way it comes. If it doesn't fit you, get something else. You can change/add a pad, etc., otherwise leave it alone. If you can't handle the recoil, get something else. No double should ever be ported. I've shot doubles with recoil reducers in them and am convinced that they don't work. The weight they add dampens recoil, but no more so than simply building the gun that much heavier to begin with, and the sloshing in the butt destroys good handling. A pound of weight makes an amazing difference in felt recoil.
