7.62 x 69....??...
I have never heard of that round, although I'm not saying it doesn't exist.. There are lots of fairly obscure metric cartridges.... That would be one LONG case..The 30-06 is 63 MM long... I'm thinking a 7.62 x 69 would be similar to something like a .300 H&H mag...

Would it be maybe the .300 Lapua Magnum?? I think I've seen it measured as 7.62 X 70 but maybe some call it 7.62 X 69.
Wouldn't be the first time I've seen the same round described in slightly different measurements.

Just get out some Google-fu...
I thought a typo at first as well, apparently not so. Generally, it appears that the Russians (?) may have been working with a .30-caliber wildcat based on the .338 Lapua Magnum case, using a 25- or 30-degree shoulder, depending on where you read about it.
One might assume that the experiences of Western militaries lately in the lands of dust and dirt has highlighted some limitations of the 7.62x54R and the SVD/Dragunov and now they're looking for something a little more ... "contemporary" for police or military use?
Ultimately though, two entirely different rounds. the first number (7.62) generally denotes the diameter of the bullet, the second numbers (39 or 69) generally denote the case length - both usually expressed in millimeters. A number of cartridges common in the US have such a metric designation, the most common being .308 Win (7.62x51mm) or .223 Rem (5.56x45mm). Even the .22 Hornet has a metric designation of 5.6x35R when found in Europe. The "R" indicates a "Rimmed" cartridge case.
