I have some XM556SBCT3 on hand I'd like to vet in my rifles. From what I gather, this is XM556FBIT3 from Doc's list optimized for 11.5" SBRs. Would it still provide adequate terminal performance in 16" barrels inside, say, 100 yards?
Apologies to those sick of discussing the minutiae of this family of rounds, but I'm not exactly a ballistics genius.
