I agree with you. There's a reason why we flinch with those muzzlebrakes. Because our biology has never experienced the force of a 250 grain projectile moving at 3 times the speed of sound. The shockwave and pressure wave moving through the air is unlike anything we normally experience.
Our body is trying to protect itself, but we ignore it. And mark my words, all these people buying these "PRS Rifles" with rearward 3-port muzzlebrakes will have severe tinnitus and shooting anxiety in about 5 to 10 years.
These rifles are pushing upwards of 175 decibels. I shoot a 338 Lapua, take it from me. If you cannot handle the recoil and need a muzzlebrake, then you bought the wrong gun!!! There's a reason why the military's sniper rifles are 15+ pounds! I have a Weatherby Mark V in 338 Lapua that is 9 pounds. I bought the wrong gun!
