First built in 1973 and discontinued in 1983, this single shot rifle was initially offered in .22-250, 6 mm Remington, .25-06, and .30-06. .243 and 7mm Rem Mag was added to the standard rifle line and a .45-70 version was added on a heavier frame.

It is a rifle that is chambered for a .30 in. diameter projectile (.30 caliber) fired with a case , primer,and powder load designed in 1906. It was designed for the US military to replace the .30-40 Krag with the intention of closer approximating the ballistics of the 7 X57 mm Mauser cartridge used by the Spanish forces in the Spanish-American War. It remained the first line US battle rifle caliber from the beginning of WWI until it was retired in the 1970s. The actual diameter of the projectile is .308 in. The caliber lives on to this day as the .308 Winchester, 7.62 X 51 mm NATO, with a redesigned cartridge case allowing it's use in NATO weapons. The ballistics are only slightly less than those of the venerable .30-06
30 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?
25.4 mm = 1 in; 30 mm = 1.181 in
They're different cartridges. The 7 mm Mauser a.k.a. 7x57 mm a.k.a. .275 Rigby, developed in year 1892 in Germany, uses a bullet of 7 mm / .284" in diameter, while the .30-06 is a 7,62 mm/.308" bore caliber. The .30-06 has a bigger case and thus is a bit more powerful. For all practical purposes, both calibers perform rather similar. They're versatile, accurate and highly successful in the game fields, provided the hunter behind the rifle does his job. For non-dangerous game hunted at reasonable ranges either one serves well.
