Home Forums Hunting & Shooting Mausers and Military Rifles Can I use a Santa Barbara action

I have a SB action and was wondering if you have/could or would build a 338 Lapua or 30 Nosler on it.
1. Will these calibers fit into the action magazine area?
2. Will the action handle the pressures of these calibers.
3. Is this something that would be safe?

Any help would be appreciated.
