I’ve read that in a hypothetical scenario with perfect hearing protection, your skull attenuates about 40-60dB of noise. Meaning that you subtract 40-60 from the noise exposure to get your “real” exposure. That’s one reason why recoiless rifles (that generate upwards of 180 dB) have daily firing limits. The other reason is that the shockwave can literally concuss you.
For guys who aren’t shooting recoiless rifles, idk how much of a “shooter’s headache” is from recoil and how much is from blast. But I do know that even single un-muffed/plugged shots taken while hunting are very very bad for you
Yes, literally concuss is what happens from aggressive side port brakes.
By design, they direct a massive amount of gasses through the side ports to provide recoil reduction. Anyone sitting on the next bench over knows.
It’s not recoil. Recoil from a suppressor is “more” than recoil from an effective side port brake. So, it isn’t the recoil. I can shoot all day with a suppressor and go home happy. As soon as a friend comes with a brake, under a roof, concrete floor and benches I have to watch to avoid them. Move a couple benches, barricade myself away, etc.
When spotting I step out from under the roof because the blast makes me flinch. I can’t spot brakes rifles hardly at all at the range because it is contained.
It’s most definitely the concussive blast from abusive side ports that gives a headache.
A match consists of about 85 to 100 rounds, with six in your group, that is hundreds of rounds in a day. We have to help time and run the local matches, so we are right in there. Sometimes you get even more from the group 30 feet to the side of you depending on the range.
At matches, I switched to a suppressor and when my chore is over, I retreat at a safe distance from the blast.
It’s not something made up at all. Not everyone gets a headache. Maybe I get one cause of all the concussions I had playing football in high school.
I suppose the fact that I tend to shoot a lot more than the average means I have more exposure to notice it and I am verified as a big baby.
