The hole in the end of the brake I feel is too large (about .390) and it needs a larger expansion chamber.
After firing about 20 shots through it, you can see a lot of powder residue on the front half of the slotted section but not much on the rear of the slotted section and none on the small holes close to the muzzle.
This leads me to believe that most of the gas is going straight through with only a small portion being deflected sideways.
I might try and get hold of a DE or Holland radial brake and see how they compare. That is if I can find one here in Australia.
