I have heard that the Holland Brake is excellent at reducing kick but is pretty loud.
I have also heard that the OPS break is supposed to be every bit as effective as the Holland but quiter to the shooter due to the angles machined into the openings which are supposed to reflect the sound out to the sides rather than backwards toward the shooter.
This would be pretty important to me, ear muffs or not.
The Holland does look more pleasing to my eye. The 3rd brake that I hear is very effective but also loud is the JP Bennie Cooley brake.
Has anybody tested/compared these brakes and can say with any certainty that one is quiter than the other?
Still undecided whether or not to put one on my .300Wby Ultra light.
I had the KDF style on my older Mark V .300 weatherby and although it reduced kick, it was freakin so loud that I swore I would never get one again. If you shoot off the side of a steep mountain, all that noise bounces right back into your ear and can give you a splitting headache for several hours.
