Depends on the application. If you mean power, the higher the caliber, the more powerful it is. for example, a .22 caliber rifle is much less powerful than a .50 caliber rifle.
Depends on the caliber
That depends on the exact model of rifle.
The M21 and Enhanced Battle Rifle are two different variations of the M14 rifle, both of which are very much real.
The 1883 22 caliber colt rifle is valued at $2,275 in excellent condition. I fair condition it is valued at $775.
Depends on exactly which rifle(s) you refer to.
Depending on condition, about the same as any Marlin 70 rifle.
