I'm looking for muzzle brake recommendations for a 28 Nosler and a .308 Win. bolt action hunting rifles. The objective is to reduce recoil and muzzle jump to see the bullet impacts. Both guns have carbon/stainess sendero contour barrels and can take up to a 3/4-24 thread. For the 28 Nosler, I've looked at the Muscle Brakes and the MBM (Muzzle Brakes and More) lines of brakes. Both of these brands have several versions available. MBM is working on a TI brake which might go well with the carbon/stainless barrels. My .308 barrel is only 18 inches long. The Precision Armament M4-72 brake seems to provide excellent recoil reduction but I'm wondering if the sharply angled ports would direct too much blast to the shooter from an 18 inch barrel. I haven't used any angled ported brakes so I'm looking for comments and suggestions. What muzzle brakes would you recommend for these guns?
