RE: .30-06
You must understand that it could be anything.....It's clear that he don't know what it is....
Don't offer a dime until you've seen it.....it just might be a p-17 or springfield.....
If it's a Rem 700 or a Win 70 in good shape (ignore the scope) I'd offer $350.
Both in .30-06 are superb arms and will last you a lifetime.....but you need to see the gun.....It's clear that he don't know what he has.
