Vais is supposedly a quieter muzzle brake
then Hollands and the like. However if you live in dirt or sand conditions and shoot prone, the holes all the way around VAIS will kick up dirt/sand and give you and your scope/rifle a nice bath every shot. Which woudl get very old real quick...
are loud. Theres no way around it. If your going to get one, you might as well get the one that takes the most kick away as thats its primary purpose, which is why you want one. There all loud and your ears wont notice the difference of wahts louder or quieter anyways. They'll all ruin your hearing.
I've shot quite a bit of times with no muffs or plugs from my 25-06 that had a holland style brake, and my 7 RM that has a Holland QD brake. I've also shot my 338 EDGE with DE brake a few times with no hearing protection. Sometimes you just dont have the time to put in muffs. I know I'll regret it later in life, but what can you do?? Cant let them wily coyotes get away and they dont stand there and wait for you to put in hearing protection, thats 99% how and why I shoot my rifles with brakes w/out protection. When I'm hunting I dont wear ear muffs, I like to hear my surroundings. When you shoot at an animal you dont notice it anyways...Untill a couple hours later or the next day LOL.
