A number of people make that spiral flute muzzle brake design. Seems to reduce recoil okay but has a strong concussion/back blast to the shooter. I removed the one I have and went with something else because of the blast.
My all time go to caliber back in the days when I carried a rifle was the 300 Win Mag and 180 grain partitions.


Great gun and we are looking forward to range reports. Whether its the photo I do not know but it looks as if the beginning of the exit hole to the muzzle(inside) is beginning to roughen up.
