A 7mm measurement is roughly equivalent to the width of a large pea or the thickness of a pencil lead. It's a small size often used in contexts like jewelry (for gemstones), Photography (lens sizes), or in scientific measurements. Visually, it may be hard to discern without a ruler or a comparison object, but it is noticeably smaller than a centimeter.
Incomplete question needs more details for an answer
what to look for
Look on the receiver and barrel.
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
No, a 6.284 does not use a 7mm cartridge. The 6.284, often referred to as the 6.5-284 Norma, is specifically designed to fire 6.5mm bullets. The 7mm cartridges, such as the 7mm Remington Magnum or 7mm-08, are different in diameter and design, intended for 7mm bullets.
havent you seen corn before? its yellow and small.............
DO NOT DO THIS!!!! The OAL on the 7mm Mag is 2.5 inches and the 7mm Weatherby is 2.55 inches. SInce they headspace on the belt, and due to the freebore in the Weatherby, the 7mm Mag may chamber in the Weatherby. SAAMI lists the 7mm Mag/7mm Weatherby as an unsafe combination one will probably chamber in the other. DO NOT SHOOT UNLESS YOU ARE SURE YOU HAVE THE RIGHT AMMUNITION!!!!
In the firearms industry the bore of a 7mm rifle is .284in.
