Please excuse my ignorance. I'm a bit of a FNG. I have never used a muzzle brake unti 2 years ago when I bought a .30-378 with an Acubrake on it. The difference was unbelivable. I could actually see the deer flip through the scope. I always use hearing protection at the range but left it off while hunting on my first trip to the woods with this gun. 1 Buck, 1 doe and a yote latter I am near deaf in my left ear. Since then I have forgot my muffs at the house but rig something up to cram in my ears once in the field. Long story short I have recently got a 300 WM w/o a brake and am looking for a quiet brake. It seems like an oxymoron to me but some claim to have figured out the physics (i.e.. Vais, Gentry, Holland). Anybody have any wisdom to share? Thanks...
