New Army "Caliber Configuration Study"

[BluntForceTrauma]

Tony, perhaps I wasn't clear, but what I meant is that I'd like to postulate a 6.5 M855A1, with its two-part copper and steel construction, that exactly matches the shape or form factor of the 6.5mm 112gr GS Custom monolithic in order to preserve that bullet's BC, as nearly as possible.

Photo concept attached.

Nincomp, thanks, valid points. The 7.62x54R BC of 0.381 I quoted is, supposedly, translated from Russian military manuals. I might add that it could simply be the GS Custom bullets are too pricey for competitors?

Anyway, as always, my main point is that these hypotheses look promising and I wish I had money to burn playing them out!
