New Army "Caliber Configuration Study"

[Tony Williams]

The problem is, http://7.62x54r.net/MosinID/MosinAmmo.htm shows the BC of steel-core, light ball varying from an incredibly low 0.242 to an unbelievably high 0.538, depending on where and when produced.

And to add to the confusion, I found this info on THR:

148-gr steel-core ball, 57-N-323-S: 0.381 G1 --- 0.192 G7 --- 820-835 m/s http://www.thehighroad.org/archive/index...19407.html

I presume that there is some confusion between G1 and G7 BCs. G1 figures are approximately double the G7 results.
