Metric designation. Some calibers have both a metric based and imperial based designation, some only have the metric. 308 winchester for example is also known as 7.62x51. The 7.62 refers to the diameter of the projectile while the 51 refers to over all length of the Case.
Like mentioned, 7.62x54r is Russian. 7.62mm bullet, 54mm oal and the "r" indicates it's a rimmed cartridge.

Insert argument about differences between .308 winchester and 7.62 x 51 here, along with anecdotal stories of many that have interchanged both calibers, and end with a catastrophic failure photo from another questionable source...

That should read the length of the case.
The R is important and doesn't mean "Russian".
Otherwise 7.62x51R would be a Russian calibre when really it's the metric designation for .30-30 Winchester.
Most European calibres are simply known by their metric dimensions.
Ex.
7.62x39mm
5.45x39mm
6.5x55mm
8x57mm
9.3x57mm
9.3x62mm
7.5x55mm
There are other names, usually country or manufacturer who created it, but they aren't used as often as with modern American cartridges.
It's kind of like old blackpowder American cartridges like .32-20, .44-40, .45-70, .50-90, etc. You can add the company name but it usually isn't required; everyone knows what you mean.
With modern American cartridges the name really is important. You can say you're shooting a ".300 magnum" but is that a Winchester or Weatherby?

So much wrong in your reply
Just adding to the info above, despite the fact that both, the 7.62x51 and 7.62x54R bear the name 7.62, they do not use the same diameter of bullets. The Russian ones are a bit larger, being 7.92mm in actual bullet diameter against the 7.82 for the western .30 caliber counterparts. Not that it matters that much for anyone using the cartridge, but it may matter for anyone reloading. It is not safe to use russian 7.62 bullets in western 7.62 cartridges.
Oops read your post wrong. I was thinking "7.62x54r is NOT 3030"
Anyway here's the video I was going to share.

I'd like to see that. Standing back at a semi-safe distance, of course.

It was an expensive toy too, lol. Needless to say, when he wanted to sell, I suggested everyone avoid it, just to be safe...
I was thinking that, but was not sure so I went with what came to mind first. Thanks for the correction, Changed original post accordingly.

Or you could get yourself a Mosin or SVT-40, you've already got ammo for them anyways
