5.56x45
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.
The force of the rifle on the bullet and the force of the bullet on the rifle are equal in magnitude but opposite in direction, according to Newton's third law of motion. However, the mass of the rifle is much larger than the mass of the bullet, so the acceleration of the rifle is much smaller compared to the acceleration of the bullet.
it all has to do with the combination of the barrel lenght the size and weight of the bullet and the speed at which the charge propelles it. Depending on this, is the lenght of the straight line before dropping.
it depends on the rifle. 7.62mm is the same as .30cal. the mosin nagant series of rifles shoot 7.62x54R. your rifle is probably marked with the correct calibur. Good answer. A 7.62 Nato or American rifle will shoot the 7.62x51 round or .308 Winchester round (don't try firing 7.62x51 round in a rifle marked .308 Winchester though, it's not safe.) An AK-47 fires a round called the 7.62x39 and the .30-06 rifle fires a round sometimes called the 7.62x63. As you can see, 7.62 is a popular bullet size!
Seven millimeters is just about .28 inches, bigger than a .22, smaller than a .30 caliber. The actual bullet diameter will vary a thousandth or two, to allow for the rifling in the weapon.The 7mm bullet measures .284 in.If you were to want to shoot cast bullets in a 7mm rifle the size needed will be .285-.286in.for best accuracy.
If you need to ask this you shouldn't own let alone be shooting a rifle!
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.
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.
Any 44 Rem Mag cartridge that is loaded by the many cartridge makers in the U.S. can be shot out of your rifle.If you are asking about what weight of bullet to shoot for deer size game.I would shoot a 240 grain bullet of either hollow point or soft point design for deer,black bear etc.sized game.
Rather silly question. You could, but you wouldn't accomplish anything except maybe hurting yourself. Barrels and bullets are matched in sized for a reason...so the bullet makes contact with the rifling to achieve spin which stabilizes the bullet when fired. The bullet must also form a "seal" in the barrel so that the gas from the burning propellant will push the bullet out of the barrel to achieve proper velocity. Why in the world would you ever even consider that? the .243 Winchester is a necked-down .308 Winchester, but you shoot it from a rifle chambered for .243. If you want to shoot a smaller bullet out of a particular rifle, you get a smaller grain weight of bullet. This will give you higher velocity but lower impact energy and lower felt recoil. As a side note, there is ammunition that uses plastic sabot's to allow a shooter to fire sub-caliber ammunition in a rifle. This is factory loaded ammo not basement reloader stuff. It was marketed under the "Accelerator" name. The 30-06 ammo used a 55 grain .223 bullet and achieved ridiculous velocities of over 4000fps.
Any real gun can shoot through walls. Depends on size of gun and what the wall is made of.
