As someone else already replied. Concussion from muzzle brakes is BRUTAL. And a lot of times it is so loud that even double earpro doesn’t make it safe. Sitting next to someone shooting with a brake even on a lowly 6.5 feels like you’re getting slapped in the face. A magnum-ish cartridge feels like more than a slap. Again, with all of that noise and business, you will likely shoot better with the suppressor and maybe 10% more recoil instead of the brake.
I’ve put 800 rounds downrange with a Ma-deuce in one sitting with cheapo orange foamies in. I didnt feel half as beat up as I do after sitting next to my dad shooting a box through his 6.8 western with a stupid brake on it wearing good earpro.
You’re right. It all boils down to our own anecdotal evidence. I would do a lot of crazy stuff though before I shot/took a braked rifle hunting. Without ear pro (god forbid) or even with marginal ear pro, you are asking for some weird shit to happen in your inner ear, at the very least hearing loss over time.
It’s not unheard of to have serious, debilitating vertigo to the point that you can’t walk, can’t move without throwing up after muzzle blasts from braked rifles. They can dislodge a “crystal” or something in your inner ear. Royally F’s you up to the point of legitimately needing rescue. Look it up.
Slim chances, but I don’t want to chance that at 10k feet with snow in the forecast. I heard a story on a podcast this summer/fall (Working Class Bowhunter) where a guy had this happen with a muzzleloader (maybe braked, maybe not?) in a blind. The muzzle was out the window, but the sound was just enough to take him out. He almost died of hypothermia waiting for rescuers to find him, was barely with the program enough to dial 911. His first hand account was pretty scary.
