Game of all size and shape is hunted, and the calibre varies in accordance with what it is you're hunting. If you're hunting elk, you're not going to use the same calibre you would hunt squirrel with, and vice versa. A hunting rifle is simply a rifle which is used for hunting - that in itself doesn't determine what's being hunted, and it would be impossible to determine an average calibre, given that not every hunting rifle was a purpose built rifle - some hunters, for example, used decommissioned military rifles such as the SKS.
There is no one answer- it depends on the rifle. They are generally less powerful than a full size battle rifle cartridge. The M16 rifle uses a 5.56mm bullet, the AK47 a 7.62mm bullet, etc.
The correct size of the bullet that fits the rifle.
Only if he is armed with a good hunting rifle and has the proper type and size of bullet to puncture a hippo's thick skin and skull in order to kill it.
5.56x45
If you need to ask this you shouldn't own let alone be shooting a rifle!
have a gunsmith do this, push a slug of close dia through the rifle, and micrometer the bullet. this will give the true bore size.
Size of the rifle will vary, depending on make/ model. The 30-30 BULLET is larger in diameter and weight than the .243, but has less energy. This is due to a slower bullet.
It all depends on the rifle the size of the barrel and the load in the bullet. .22 Bullets come in stubby, short, long and Mag.
None, explosive ammunition is prohibited for hunting.
The M14 rifle is chambered for the 7.62x51mm NATO cartridge. The 7.62 round has a bullet diameter of 7.82 millimeters, and a case length of 51.18 millimeters.
Generally, no. The size is the same, but the mass of the projectile is not. And a .22 rifle bullet is propelled by gunpowder, with a much higher muzzle velocity than an air-powered pellet.
it may kill a deer if you were lucky. But it is not the best choice for hunting deer. Remember a .22 pellet is the same size slug as a regular .22 cal bullet and I would not hunt deer with a .22 cal rifle. It's just a poor choice.
