See Lilja's comments (article) on the "safety" issue at Lilja Precision Rifle Barrels - Articles: 378 Weatherby Cases in the Remington 700 Action?
While he is addressing the 378 Weatherby, the bolt face is the same and the 338-378 Weatherby is at a similar power level to the 338 LM.
If you want to know who is building actions for 338 LM, see the Receiver matrix at Products - Rifle Components
Me, I'd go with a .750" (or larger) bolt.
