Silly question....

Is 7.62x54 the same round as 7.62x54R?

What is the difference?
Is it safe to use 7.62x54R in a 7.62x54 firearm?

The R is for rimmed.  Did you find some without rims?

Just as there are .44s and .44 magnums which the magnum should not be used in some standard .44s, I was not sure if the 7.62x54R was the same and one of those that could not be used in Rifles that say chambered for the 7.62x54 (without the 'R')

I'm pretty sure the R is for rimmed.  I've seen it refered to as Russian but I think that is wrong.

I've never seen it without a rim.  The JAP 7.7 is what is confusing.  They had several 7.7 rounds and none of them interchange.

The "R". BTW the Finnish designation is 7.62x53R. Confusing isn't it?

7.62x54R is rimmed, and the case is tapered below the bottleneck. Kind of like a long AK round with a rim. It also reminds me of some older cartridges for lever guns. 7.62x54 AKA 7.62NATO is a straightwall case and rimless. Looks like a 30-06 with about 1/8 inch missing from the case. That's what it is. I don't think either will chamber in the other and wouldn't want to try.

COTW (Cartridges of the world) list the 7.62x53R as sometimes being reffered to as 7.62x54R,  Reffering to it as 7.62x54 is just like reffering to AR15 rounds as .223 instead of the technically correct .223 remington. 7.62x53, 7.62x53R, 7.62x54, 7.62x54R and 7.62x54 russian are all the same cartridge.
However, 7.62 soviet is the 7.62x39 round but the only people who will be that technical about it
are those damn anal retentive nit picking no-lifes (like me)
