No way to answer without a description of ALL markings.
And your question is?? The 7mm's were made mostly for South American countries such as Venezuela. Email me with a further description for more information.
not much more than its US or Japan made counterpart
Recommend you ask for assistance at your local gun shop.
Impossible to answer without a detailed description of all markings, finish, condition, box, papers, accessories, etc..
300 or so
100-500 USD or so
It should be marked on the barrel. There are other 7mm rounds besides the 7mm Mag.
that would depend on which 7mm cartridge you are referring too. ie 7mm-08, 7mm Rem mag, etc
Depends which 7mm your talking about. The only 7mm I know of that has a larger case capacity than the 300 wby mag is the 7mm Remington ultra mag or 7mm rum
7mm x 1m/1000mm = 0.007m 7mm are 7/1000 of a meter.
Browning did not invent the 7mm
