Possibly. The commercial .308 Winchester generates higher chamber pressures than military 7.62x51 does, and this may not be advisable practice for all 7.61x51 rifles. If in doubt, inquire with the manufacturer of the rifle before using commercial .308 ammunition.
NEVER FIRE AMMUNITION IN A WEAPON NOT CHAMBERED FOR IT!!!!!!!!!!!! Danger, Danger, Danger,#@@@@@@@@@@@@@@@@@@@@@
None... it is the same sized bullet (.308 diameter). You have to choose the selection of bullet when reloading 30-30 ammo for the type of bullet. A pointed bullet in a tubular magazine can present a problem when the rifle recoils. The ammo is not interchangable, you must shoot the ammo that the rifle was chambered for.
It MAY shoot. It will not shoot well. It may not shoot safely. The .243 is a necked down .308 cartridge. You are sending a .24 bullet rattling down a .30 barrel. It may or may not trap enough gas to cycle an autoloader. It WILL blow out the case mouth.
No.
No, it cannot.
It can shoot about 3 miles. It can shoot accurately to about 1100 meters in the hands of a highly skilled marksman, depending on which rifle is firing the cartridge.
many types of rifle, some pistols like the XP 100 and that is about it.
If you're using a .308 rifle, yes. If you're using it in a 7.62 NATO rifle, you need to check the headspace before you do it, because the two rounds are dimensionally similar, but not identical.
no You could use the 308 ammo in an Enfield.
Consult with the maker of your rifle before you attempt to do this. Some .308 Rifles don't chamber the 7.62NATO ammo properly also some reloaded NATO rounds may have a little too much powder load for a commercial .308 rifles parts to handle, it may not explode on the first few shots but it may be doing unseen internal damages that will lead to an action or parts failure, which may lead to injury or death.
The cartridge in question is the .300 Winchester Magnum, and not the .308 WinMag. The .308 cartridge is about 16mm shorter than the .300 Winchester Magnum casing. The two are NOTinterchangeable.
A rifle with a 7.62x51 chamber can chamber commercial .308 Winchester ammunition - putting military 7.62x51 ammunition in a rifle with a dedicated .308 Winchester chamber is not recommended. Questions regarding your rifle may be directed at the customer service hotline of the manufacturer, as some imported rifles actually do have a 7.62x51 chamber, but must be stamped as .308 in order to be importable as sporting rifles.
