9mm
The area is 254.5 mm2
yes................ Actually, it depends. There are several different case lengths that accept a 9mm bullet, so it depends on which particular cartridge you are referring to. For example, 9mm Kurtz is not the same 9mm para.
Only if it is the same type. There are different types of 9mm and they do not interchange as a rule. For example, the Walther PP fires a .380 ACP round, known as 9mm Kurz. This cartridge is shorter and not as powerful as the 9mm Parabellum, also called 9mm Luger.
Diameter = 2 x radius = 18 mm .
No. Not all 9mm cartridges are the same. 9x19 (a.k.a., 9mm Luger, 9mm Parabellum), for example, is different, hence, not compatible with other 9mm cartridges, such as the 9x17 (a.k.a., .380 ACP), 9x18 Makarov, 9x21, 9x23 Mauser, etc.
The radius of any circle is its diameter divided in half. So: 18mm/2 = a radius of 9mm
From 1976 on it will be part of the sn. For example 245RT01010 245 = 9mm RT= 1976 01010 = the 9th one made in 1976 Sns start at 01001 every year 245 = 9mm 2W5 = 40 S&w From 1998 on a 9mm would = 510
A base example is: a 9mm parabellum bullet is .356 caliber.
No. There are more than a dozen DIFFERENT "9mm" cartridges, and they do not interchange. The most common is 9mm Parabellum- also known as 9mm Luger or 9x19. It does NOT interchange with 9mm Kurz, 9mm Corto, 9mm Makarov, 9mm Ultra, etc.
No. There are several different calibers that are called 9mm. These calibers are not interchangeable.
