Do you mean the length of the cartridge or the diameter of the projectile?
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
20x110mm autocannon round.
2.5 cm and 7 mm
The 30-06 shoots a bullet which is 7.62 mm in diameter, so the 30-06 is "bigger" in that sense. Several different weights of bullet are available in either caliber, so that's an undetermined variable. There are several different 7mm cartridges (7mm Mauser, 7mm Magnum, 7mm H&H, 7mm-08), so you have to be more specific when comparing ballistics.
cm is bigger than mm, so yo're going to have a fraction. 7mm=0.7cm therefore, there is 0.7cm in a mm
The 30-06 ( say thirty ought six) fires a bullet that is 7.62 mm in diameter. The 7mm fires a bullet this is, well...... 7mm. 30-06 has a bigger bullet. The size of the GUN can- and does- vary. BTW- catridges such as the 7mm MAGNUM will have greater energy than a 30-06. So- what is your definition of bigger?
no, the 7mm is .284 bore, the .338 is, of course, .338
3006 weeks = 3006 x 7 days = 21,042 days
Basically the case is all. Same caliber bullet, but the case is shorter in the ultra mag. Its basically just a smaller round, bigger punch.
They are: 1, 2, 3, 6, 9, 18, 167, 334, 501, 1002, 1503, 3006.
It should be marked on the barrel. There are other 7mm rounds besides the 7mm Mag.
it is 3006 cal.
