It takes a lot of time and ammo to dial in a BOSS. If you plan on changing loads often it might not be worth the trouble.
As far as the muzzle break aspect goes, you should NEVER fire one unless you and everyone nearby are wearing ear muffs. They are really
LOUD.
For hunting I wear a pair of
these. I've never worn them with the muzzle break, because my BOSS rifle is a 7mm-08 so I hunt with CR, but they change the
BOOM from my 20" barrel turkey 12 ga to a faraway
boom.
