There is no doubt that the 338/378 will out Velocity the 338 lapua with the same pressure loads
because of the 20+ grains of capacity, But that is where it ends. Brass for the 338/378 is $3.89 each
and the Lapua brass is $2.57 each. It doesent make sense with the Lapua brass being better.
I am a big fan of the big Weatherbys and especally there actions but there ammo and reloading
componants have priced me out of building any more of them and moving to something else.
I still have,and shoot a 30/378 and fortunately have a lifetime supply of brass for it but I will not
build myself another one.
I have had very good luck with the 338 RUM and It will match the ballistics of the Lapua but the
brass doesent last as long. I am testing a wildcat that approaches the case capacity of the 338/378
and the parent brass is $.97 cents a round.
There are some 338 Lapua wildcats that are outstanding both in accuracy and velocity and combined
with great brass, you would be hard pressed to find something better.
A 338 RUM AI or a 338 AI Lapua will have enough case capacity to do anything you want, And the
standard 338 RUM or Lapua will also without the wild cat issues.
I do not recomend buying a complete rifle for accuracy and just shooting it even though occasionally
you may find a shooter. I feel you can build a better rifle because of the premium barrels and the
blueprinting of the action by a competent Smith.
A good Mark V action for a don er will run you $700.00 minimum.
You ask for opinions and this is mine. Build what you want and live with your decision.
