Re: Is muzzle break necessary with 38-40 lbs or recoil?
for 338 LM muzzle brake is not a ''must'' you can shoot without . I have shoot a 338 LM built on a BRNO ZKK 602 same barrel profil as the 458 mag recoil is strong but not terrific , that ok for an hunting rifle sure that if you plan to shoot lot of rounds that perhaps a problem and you need to take care of your eye/scope safety distance to avoid any hurt .
I find that except for prone shooting Vaiss brake is very good you :
you increase accuracy .
not make more noise as a rifle without muzzle brake
look is nice ( not a panzer muzzle brake )
