I broke it, and now I'm sad

This is all so very informative..........now let's throw 38 special (.357"), 404 Jeffery (.423"), 44 Spl and RM (.429"), 38-40 WCF (.401") into the fray. The reality is, the name of a cartridge, even though it may be expressed with certain numbers, does not necessarily correspond to the actual caliber of the bullet used in said cartridge and to assume it is, is sheer folly.
There is also the industry standard metric expression of 30 caliber which is 7.62, this is not a bullet diameter expression, this is the caliber designation as accepted world wide.

its been awhile ... i may HAVE been confused ... regardless .... .308 is 7.82 in diameter. They are not the same


I couldn't remember which was not interchangeable ... your not supposed to run .308 on 7.62. chamber. You can run 7.62 in .308. chamber


My numbers may have been off ... but the comment was that " they are the same " and they are not

308 Win and 7.62 x 51 are basically the same thing and fully interchangeable. Both run at about a max pressure around 62,000 psi



Your 308 dies are the correct dies for sizing 7.62x51 brass. If it is brass fired in another rifle (machine gun) it might be a little harder to size, but if properly lubed, should not be a problem.

If you broke a decapping pin, it was probably because it was Berdan primed (lacking the hole for the pin to go through.)

Or, it was some other flavour of 7.62. like a x39 or x54, which are also usually Berdan.

But can you shoot a 7.82mm bullet in a .308"? Or would that fit better in a .303?

I think that was allowed when I was a kid...but then we went metric, and it became a no-no...:)

Ask Silver Hammer; he sounded like he had a handle on all this and was happy to explain it to newbies...:rolleyes:

It wasn't all his fault, OP originally said he was resizing 7.62 Russian cases in a .308 die, and then edited it later to say it was a something else although he never was completely clear. A little knowledge is as dangerous as no knowledge on the weinernet. :)

Silver Hammer - made me think of "Maxwell's".
