I'm talking about barrels with the same caliber. South Africa at one time would not allow you to take two guns in the same caliber. I assume that is still the case. What I'm wondering is if two barrel sets will be treated as two guns. Even though you only have one receiver do they interpret it as two guns. Those serial numbers on the reciever and barrels really confuses them. I tell them to go by the barrel which is what they are used to looking at. Although my US Customs document has all of these serial numbers on it. I put the scope serial number on the custom form as well so that does seem to help as it is serial number overload.
Can you take a 9.3x74 double barrel set and a 9.3x74/12 gauge set with one receiver?
