Bighammer,

Wait till next week as a mate of mine is trying a different brake on a 300 Ultra.

I think Bob De Vried also makes brakes.

The KDF type brake whih is the type on Weatherbys are very effective and because the holes are all around the brake fitting them is a little easier. Obviously the brakes that just blow out to the sides are more critical for fitting.

The bigger diamter of the brake the more effective. If look at early Wbys they used what was called the slimline KDF type brake where the brake is the same diameter as the muzzle. The later Wbys uses the same brake but the brake is bigger in diameter than the barrel.

The brake reduces the recoil because:

1) It diverts the gas sideways and

2) The gas physically hits the material of the brake much like the wind on the sail of a boat. Thus a wider brake is like having a bigger sail.

The most effective brakes are the so called clam shell brakes. I will dig a couple of links up for you and post then. The Clam Shell is often seen on the 50 BMGs and tactical type rifles in calibres like 338/378. They are very wide and rather than just divert the gas sidways they direct it backwards, sort of like a jet using referse thrust on landing. On something like a 30/378 these type of brakes almost make the rife go forward on firing.

Mike
