>>Post picture of PKM outputting 7.5 inches cone at 100 yards while firing bursts.
That is not "7.5 inches cone". This 25% hits strip horizontal (Bб) and 25% hits strips vertical (Bв). Total size of dispersion circle is x8 of them.
For PKM fired from bipod 5 rds burst average shooters it is
1.52x1.04 meters or 60x41 inches. horizontal x vertical.

>Did you seriously miss the part where, while PKM table uses meters, the SVD table uses centimeters for its values?
You are missing what value Soviets quote. They dont quote "groups" aka diameter of the circle that holds all hits. They quote strip that holds 25% hits vertical or horizontally.
