Re: muzzle break question
No idea what kind of muzzle brake you're having installed but all muzzle brakes are "loud" and must wear ear protection with or without. There are lots of effective muzzle brake designs out there with varying effectiveness. Site sponsors have very effective muzzle brake designs.
If you do a custom search (top right corner), you'll see plenty of results to include a poll.
I use a Holland's QD and a custom made similar to the QD except with 4 ports on my .300 Win Mags and both have felt recoil similar to .243s.
