What is the ballistic coefficient for the average 7.62x39mm round that you might find in a box of Wolf or Brown bear? Aren't these rounds essentially the M67?

The Hornady 123gr SP has a BC of .252 or thereabouts. I would not expect any better (nor much worse) from military FMJ.

I'd say that the B.C. for M67 is reasonably close to what you can expect to find in the commercially available ammunition.

B.C. for M67 = 0.243 (G1) good
B.C. for M67 = 0.164 (G6) better

B.C. for M43 = 0.185 (G5)
