 What caliber can be re-chambered to .338 Lapua?

I know it is possible to change rifle calibers by re-chambering the barrel. Does anyone know what caliber can be re-chambered to .338 Lapua?

Here's what I'm thinking. Why pay an astronomical sum for a pre-made "tactical" .338 Lapua like a Barrett 98 Bravo if you can take a good, less expensive rifle, rechamber or even re-barrel it with a match barrel, and keep the same bolt? Accurize it and add a good stock by a good smith and presto, tactical rifle for less than $5K.

Any ideas?

A few problems.

First is the action length. The Rem M-700 LA is almost a bit too short. It can work, but it's not ideal, so score one for the purpose built actions.

Secondly, you need to open up the bolt face, which is a bit easier, but the standard magnum bolt face is too small.

A 338LM round is roughly 3.675" long and that's generally seating to mag length in the AI and Sako platforms.

It's not as easy as you think it is due mostly to dimensional issues.

You can rebarrel .378 Weatherby and .416 Rigby actions.

Just get one of these and be done:



Sako TRG-42s

IIRC the 338 Lapua is derived from the 416 Rigby case.. it was originally known as .338-416.

Yes. But thicker brass, annealed and hardened where it's supposed to be.

Or why not do this?
Buy a Lawton, Stiller or Badger action - $900-1200, AICS chassis - $800-$1100, Kreiger Barrel - chambered, fluted, threaded (both action and muzzle brake), your choice of twist 1-9.35", - $950; Jewell Trigger $230, Inletting the AICS stock for a larger action (Badger) - $120. Muzzle brake - (Surefire $190) and then get a coating on it (Cerakote, Duracoat, etc..) - do that yourself.

About $3700 for a great rifle that can handle the 338 round versus the 3K you put into a standard Rem LA that may or may not be able to handle the round well. Lots of guys have trashed Rem Mag Long actions using 338LM in them.

The Badger M2008 has a built in rail so you won't need a base either. And it's built like a tank...

I went with this over the Sako setup because I wanted the custom twist, and folding (AICS 2.0) stock. And if I added an extra Sako magazine, Bipod, muzzle brake, it was about the same cost. The Sako folding stock is about $1200.

But the TRG is one hell of a shooter. Like Chis said, go the for the action that is made for it or just buy the TRG.

I would not trust a modified remington bolt, or the action to handle the power and bolt thrust generated by the .338 LM.
There is a Remington .338 Ultra-Mag that is close in horsepower, it is a rebated rim design based on the .300 Ultra-Mag.

By the time you buy the action and pay for the work, pay for the stock, your out as much as a new TRG-42 (less than 2900 from Buds). With the TRG you have a purpose built rifle for the round, not an altered and weakend 700 action and bolt.

It's your face and head, do what you want.
