As Otto said the m98 will work just fine. I've been using one since 1976.
; Also, the action rails will have to be opened slightly, the bolt face opened up and extractor ground back and re-shaped slightly.
; The bolt should be cut off and a new one welded on to allow an action mounted scope if that's a goal.
; Since you already have the action, action cost isn't a concern. The above work should not cost more than about $100.00 if you have to have it done, but undoutedly, some gun smiths will want more.
; Were you to re-barrel and chamber for a .338/06 IMP to .375/06IMP, the action rails and bolt will function just fine, and only the bolt replacement and scope base holes drilled and threaded.
; The .338/06IMP, with a 24" to 25" barrel will come very close to .338 Mag factory ammo, while the .375/06IMP will come within 50fps of factory .375H&H ammo, my last two have quite easily. Incidently, the .35/06IMP can exceed the original .375H&H ballsistics by up to about 75fps.
