How much do you want to spend?

The McMillan is twice the cost of the B&C. I have both, but more B&Cs than McMillans.
If you go with a B&C I would recommend the "Accumark" or the 9 lug "free float" version. This will allow you to free float the barrel much easier than buying the one for a #2 barrel and hogging out the barrel channel.

Bed the rifle in the stock and enjoy!

Could you rebarrel a .300 Weatherby Action to a .338 Lapua?
Probably need open up the bolt a little.
Why go trough that trouble if you can go for a 338wm with a barrel swap alone?
400fps more for a 200grain bullet?
What do you want to kill and at what distance?
If trouble or cost is not an issue 338 Lapua and Norma are in my opinion better cases.

Over the years quite a few have used the (Mark V ) action for 30x378s due to the large bolt diameter.
It works well for the 300 Norma also.
If you have the action, thats one thing, but if you need buy a gun for the action it then becomes another thing.
With the cost of some of the new custom actions today it makes little sence to by a Wetherby just for the action, and still be lacking as for an action.

Most likely will not be a hunting rifle. Probably more of a long range target rifle. Ive always wanted a 338 Win but the Lapua seemed to have more speed. But looking closer.....with a 225 gr bullet the Win mag might be 2850 fps and the Lapua 3000-3050 fps?

If thats all the difference I think the Win mag is a no brainer.

I've already got the rifle. Pretty sure the barrel is shot out. I started this thread inquiring about the possibility of a rifle build on the Mark V action and the concenses seems to be that is a hell of an action.

To be both rational and booring then I guess you already has lots of 300weatherby brass so necking this up to 338wm would be a cost reduction.
I bought a 300 myself as a donor and had it chambered for 7mm practical. Long magazine so had no feeding problems when seating bullets far out.
From what I understand it can handle all the calibers that are offspring from the 375 beltet H&H
You don't have to get new brass and you don't need to pay for having the boltface opened up.
Also winmag reamers is probably available at whatever gunsmith you droop by.
My two cents..

If you find an reamer for improved I guess you would make up more of that difference.
I little more holdover at long distance don't matter much for target.
Think your at the limit anyways if that little exstra speed make it a go or nogo on any game.
Take it to a smith and ask to get a quotation and ask him if there is any other caliber he would have chosen and see if he can convince you to do something that make u feel the extra cost of new brass and machining of bolt is worth it.

EDIT: forgot there is an 340 weatherby and that would take you past wm velocity and you can order barrels from weatherby I guess unless you wanna go trough the trouble to get a 340 improved reamer for better headspacing. Still think you could reuse your old 300 weatherby brass.

Ive been watching bullets fly across wide windy valleys for a very long time at this point.
As we all know, we can dial a modern scope in order to make many cartridges make the trip.
But just making the trip is where all the similarities end.
All 338s are not created equal just because they can use the high BC 300 gr bullets.
In fact some might actually perform better by not using them.
If you improve the 338 Lapua case, you will end up about where you would start out by using a 378 case,
or a 416 case. and of coarse you can also improve those cases.
But you still wont have what you would have with 408 size cases.
And that creates issues with your present loading equipment, as in large enough.
So there is much to consider, but if you were to watch them all fly on the same day, you will know at least where they are in order of performance.
I doubt any gunsmith is more up to speed on 338s than Bruce Baer from Willow Hill Pa. which is an exit on the Pa Turnpike.
If your serious, id at least recommend talking with him.
