In my old age I've gotten where I really hate recoil but I have some large guns I like to shoot, including my 375 H&H.
I also do a LOT of '06 shooting with vintage US Military Rifles, M1, M1903a3, and M1917, also my Mosin 91/30. All with steel butt plates.
What does work is the Buffalo Arms Recoil pad. You never know its there but it really helps with the recoil.
I'd recommend getting one and using it for all your shooting. When you go hunting, you wont notice the recoil for the 2-3 shots you use.
Using this recoil pad will help eliminate flinching caused by recoil.
