[QUOTE="Edd, post: 1601694, member: 30592"] I have an opinion based on information I have gathered from people that should know the facts. The contour of a Model 70 338 Win Mag barrel is not going to be suitable for a 338 Lapua. Starting at the chamber end, you need a 1.125" diameter tenon thread for the Lapua. For that thread diameter, the diameter of the barrel needs to be a minimum of 1.300" on the chamber end. The diameter of the neck for a SS barrel, measured 6" from the bolt face, should be about .950". The muzzle diameter should be about .800" for a brake. [/QUOTE]
