PRB MUZZLE BRAKE Sound TEST: https://bit.ly/2LcYf1H

So the brakes INCREASED noise levels hugely. The dB Scale is actually logarithmic, so the true sound level perceived by the shooter is much greater. Cal Zant, PRB editor, did a conversion of the dB increase to actual perceived loudness, using an accepted scientific formula (see below). For the rear position, increased sound loudness levels were 41% to 162% greater, with the average about +110%, i.e. more than TWICE as LOUD.

We list this information above, because the comments by John are not only completely misinformed, arrogant, and wrong, but they are also dangerous. We see this kind of thing all the time — where an arrogant and misinformed self-proclaimed expert talks nonsense. It is doubly ironic that John asserts that “the idea of a muzzle break [sic] increasing the volume of a muzzle blast/report is false and is a good example of people spreading bad information with no real science to back up the claim.” In fact, it is John who is totally, completely wrong. And the REAL SCIENCE, done by the PRB, proves John is the one who is absolutely wrong, as wrong as can be.

FWIW, we have logged John’s email address and IP and he will be banned from commenting on this site ever again. Lesson to readers: If you want to call other people out, you better get your facts straight.

—————- FALSE READER COMMENT —————–

John claims:
“For the record muzzle breaks do not increase the db or spl of the muzzle report. It changes the freq. and can alter the directional slightly but it actually lowers the db and spl. If people used an empirical measuring tool and did not parrot bad info this would not be so controversial. Human hearing is a terrible tool when it comes to judging the spl or db of a sound. If a pitch is increased from a low note to a much higher note but adjusted to keep the intensity of the sound the same people will perceive the increase in pitch as an increase in volume. The reverse is also true. We hear with our brains more than with the ear as it is so it is not hard to fool human hearing. So the idea of a muzzle break increasing the volume of a muzzle blast/report is false and is a good example of people spreading bad information with no real science to back up the claim. Perception of an increase in volume is not the same as an actual increase in volume.”

Editor: There are a variety of reasons, one simply being “ain’t been done before”. Other important factors expressed to us include: 1) The expense of suppressor (and tax stamp) would a significant cost to a match rifle (which is already expensive); 2) Suppressors are not legal in all states, so that would require match rule variations in different jurisdictions; 3) If suppressors proved to bestow a competitive advantage, this would create yet another “hardware race”.

You are living in a self-righteous bubble if you think brakes should be disallowed everywhere and that brakes are only for guys shooting ‘…to big a caliber.’ (sic)

Even the lowly .300 WM is “wearing” on a shooter. Except in very heavy rifles, cartridges north of .30-06 recoil need a brake and/or can to be accessible to most shooters, and I’m not even getting into the other reasons to brake a rifle.

It is your kind of thought pattern that is killing NRA Highpower, and what makes it, and clubs like yourselves, so da^%ed unapproachable that people just won’t.

We’ve made our own bed for the last ? decades, and sure enough, people will find a different way—and NEW set of rules—to enjoy long range shooting.

PRS is one of those, and I can’t say I blame them.
