My father in law is interested in a .338-378 but wants a wood stock. I see the accumark model and mark 5. Not sure if this caliber in a vanguard but question is. Is the accumark a older discontinued model or renamed mark 5. I can only find wood stocks so far for the vanguard and mark 5. At one time I thought I saw on Weatherby web site one could get wood stocks? Can anyone tell me which models the . 338-378 comes in and possible wood stock available.
