Just follow safe loading practices as you would with any other gun. You should of gotten Browning literature with a suggested sweet spot for the cartridge and bullet weight you are using.
I've had the opportunity to shoot many A-Bolts that were BOSS equipped and it has never failed to produce exceptional accuracy for an inexpensive out of the box rifle.
Never thought they were louder than any other brake. If you do the Conventional Recoil BOSS is available and I beleive is included with the new A-Bolts
