500nitro - Examples:

out of regulation (badly)

Maybe Rigby designed a good action, but I have seen some that did NOT stand the test of time. So I am not convinced that an old Rigby is any better than a new Rigby. In fact, based on the rifles I have seen, a vintage Rigby would be a very high risk purchase.
