A muzzle brake will reduce recoil on all calibers, but some more than others. Let's take a look at the components of recoil. One part is action - reaction. The bullet goes in one direction, the rifle in the other. Another component is the jet effect, caused by the gasses shooting out of the barrel and driving the gun backwards like a jet engine. The muzzle brake only works on the jet effect component.

Muzzle brakes work best on cartridges that have a large case volume to bore volume ratio and high pressures for a strong jet effect and relatively low bullet weights, such as a 7mm Magnum. It won't work nearly as well on a 45-70, which has a large bullet weight component, a low case volume to bore ratio and low pressures. It would work pretty well on a 338 WM, but the bullet is still heavy and still going pretty fast.

The problem with muzzle brakes is that they work by siphoning some of the gasses of to the side so that they don't act like a jet engine pushing the rifle backwards. This causes a good deal of the noise to go to the side instead of forwards. This raises the volume level for the shooter and anyone around him considerably, well into hearing damage territory.

NEVER fire a rifle with a muzzle brake without hearing protection, and yes, I DO include "just once" for hunting.

When in Alaska I owned a 338Win Mag Weatherby Vanguard stock out of the box syn stock was very sweet shooting, Did not need anything to reduce the recoil. Then again I shot 540 grain HOT loads all the time in my 45/70. not sure if being 6 2 and 285lbs makes a diff in felt recoil.
