Re: 338 Lapua...loads...info etc.
Wby comes with 26 inch plus brake. The barrel contour is the same in 30, 338, 378 and 416 at about .71" at the muzzle.
I will fire some shots from the factory 338/378 and then have a barrel of similar contour in 338 Lapau out on. Some testion then of the 338 Lapua and then rechamber to 338/378.
I will have the barrel threaded to take the brake that comes with the 338/378.
I am getting to the stage now where I wear ear muffs and plugs with anything that goes bang, soI may as well have the brake being used.
My feeling is however, that the 358/378 will be the best, although not in the context of this forum. Not a typo, 35 caliber on 378 case.
