hi guys i have a question a head of 303 caliber is 7.7mm can i use it in a 308 rifle ?

because the 308 is 7.82 i think i can use them. what do you think guys ?

 

[Saskshooter]

Absolutely not.

If you have to ask that question you really need to put the rifle away and get somebody who knows what they're doing to school you a little on firearms.

I don't mean this to sound rude, but it's obvious you have little or no knowledge of firearms safety... Doing what you are asking could very easily kill you.

Guys be civil.

My apologies if my response came across a little brash...

However I feel that a question such as this should be met with a somewhat "firm" reprimand, if for no other reason than to get the point across.

I believe (as I'm 100% sure you all do) that it is the responsibility of any gun owner to know how their firearm works. I understand that some are more competent than others, but using the correct ammunition for your weapon is one of THE most important rules of firearm safety. The fact that the OP asked his question in the first place leads me to believe that he has no knowledge of the "Rules of Firearm Safety," and should most certainly acquaint himself.

Here is the NRA page for the Rules. There is a wealth of other great information here as well.

To answer your original question a bit more gently...

The 303 British, 7.62x54R, and the 7.7 Arisaka (Jap) all use .311" bullets, whereas the 308 Winchester uses .308" bullets and its metric designation is 7.62x51.

Loading .311" bullets in a .308" bore is very dangerous! I

It is quite common to reload for those older .311" military rounds with .308" bullets, because they are readily available. What results is safe, although oftentimes not very accurate.

The most important thing to grasp from your question is to ALWAYS use ammunition that matches your firearm. If you not 100% sure of what you're doing don't take any chances; just look at the headstamp on the brass and make sure it is exactly what is marked on your gun.

Merry Christmas.

And it's better to ask, then do something dangerous. So there is no problem with the question as asked and glad we could help.

Smart move, always ask when there is any doubt. I know guys missing eyes, fingers and other body parts because they thought they could do something they shouldn't have tried.

As for the 308, it's not 7.82, it's 7.62, making the barrel diameter smaller than a 7.7 bullet. So, even even though you probably could have never gotten it to chamber, because a 303 is a totally difference designed cartridge and would not go in the camber, had by some unknown way you managed to do it, it would have blown the whole rifle to pieces right in you face.

I think by 'head' he meant the .303 bullets, not the entire cartridge. But yes, they are too large for safety.
