Military round comparisons

[SHORT-N-SASSY]

That sure makes 6.5 Grendel look great. Unfortunately, using specs for the Lapua HPBT Match projectile paints an exaggerated picture of Grendel performance with any likely military Ball load. The closest commercially available analog to M80 Ball is the Norma 120gr FMJBT, with a 0.420 BC. Plug those numbers into a ballistics calculator and the result is not nearly as impressive.

stanc,

With all due respect, the "6.5 Grendel look[s] great," because that's just what it is --- no matter how you slice it! And, lest we forget, the Grendel has entered this AR game, not without a significant handicap: while the 6.5 Grendel respects its "self-imposed" 50,000 psi to 52,000 psi limit, the M855A1 unabashedly takes it up to 63,000 psi! --- M855A1: Should if be the New Round for Soldiers and Marines? (http://www.gunsandammo.com/.../m855a1-sh...nd-for-sol...). . . I'd like to see the 6.5 Grendel in the soon-to-be-released ARX100!
