Re: Which Weatherby Mark V rifles can be used to build a .338 Lapua?
I just did what you are talking about doing, I bought a mark v weathermark for $800 it was a 300 wby. I ordered the mag box, the follower and the extractor from wby for another $100. Add in a new stock for $400. I went with a bartlien 1 in 9.3 twist 338 barrel carbon wrapped by proof research that finished up at 27.5 inches, and a muscle brake style titanium brake. We chambered it to 338-378 wby but with no freebore. i went with this chamber choice for the reasons mentioned before and also because the guys I shoot with shoot lapuas and lapua improveds. I have been very impressed with their rifles and I don't think my choice is better but it is "different" and so we still have something to argue about! I am only 9 shots in and the weather has been to cold to get out much, but I will say the chrono numbers were even better than I had hoped! Time will tell if I made the right choice but for now it is fun to find out. With the cost involved the accu mark in 338-378 may be the best place to start, at least you could play with this caliber while you gather all the parts for the rest of the build . good luck to you.
