If you need to ask this you shouldn't own let alone be shooting a rifle!
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.
5.56x45
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!
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.
The M14 rifle typically uses a 7.62×51mm NATO cartridge, which is commonly referred to as .308 Winchester in civilian terms. The bullet diameter is approximately 7.62 mm, or .308 inches. This caliber is known for its accuracy and effectiveness at longer ranges, making it a favored choice for both military and civilian shooting applications.
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.
Your Winchester model 25 rifle will take any size scope that you see fit to use as long as the rifle is drilled and tapped for scope use.If your rifle comes with a 3/8in.milled receiver rail then you must use that size scope ring bases.I recommend that a good 4X power scope is all that is needed for the effective range of .22cal rimfire ammo.
the size of Winchester is not that big but has a respectable amount to do and is a great tourist holiday with lots of attractions such as open ground fairs.Winchester 70 is the model of the gun, 7mm Remington magnum the cartridge size. 7mm is a good sized bullet and will kill anything on this continent.
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.
