Well, like the 7.62 x 54R, the 30.06 shoots a 7.62 round. The 30.06 shoots essentially the same weight bullet at essentially the same velocity as the 7.62 x 54R. It does so from a case about 54 mm in length. But it is not a rimmed case. So you find it sloppy to call it the "Russian 30.06"?
Well I do yes. Probably because I take a historical connotation in the description, and the historical link is not there. As I pointed out earlier, one can compare the ballistics of almost all .30-.32 cal medium to long case cartridges and declare them "the same" if a difference of a few hundred fps doesn't bug you. To say they are similar can be useful as a frame of reference. Getting back to the Russians, the Soviets flat out copied many things, like the B-29. Thus, that is what I'm thinking when I hear "Russian .30-06". To a neophyte, I might describe it as a .30 cal rimmed case, with a length between that of an -06 and a .308. But that's just me. Depending on their level of knowledge, I might also say its a shiny thing that goes bang. :-)
