Depends on what is marked on the gun.
A metal shell holder that holds two or three additional rounds to the side of the gun.
Not possible to answer without more information. Many military cartridges are headstamped with the date and place of manufacture. That does not tell what the cartridge IS.
Depends on how fast the gun that shoots 700 feet gets it projectile to 700 feet.
This is a shotgun with an internal barrel diameter (called the "bore) of approximately .410" which shoots a shell which is about .410" in diameter. It is the only shotgun shell size that uses this convention. A 12 gauge shotgun, for example, does not have a bore of "12". A 20 gauge shotgun has a smaller bore than a 12 gauge and a 10 gauge has a bigger bore than a 12. Gauge size is based on the number of lead balls of the bore diameter which are required to make a pound (16 ounces). 10 balls, 12 balls, or 20 balls.
