338 lapua barrel contour

[Bounty hunter777]

Hi ,
I am planning to build a hunting 338 lapua rifle and was wondering what is the lightest contour I can do ?
I saw a model 70 SS in 338 win mag and likes the light contour they made..Is it safe to have it done with 338 lapua?

Do you intend to have a muzzle brake installed?

Yes

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.

You may want to look at a carbon fiber barrel. That's what I did with my 338 edge.

I think there will be chronic compatibility issues between 338 Lapua and cheap.
