Kchuntis,
Extrapolate same to a 21" FC 243 Kreed' and a .620 BC 112gr at 3050fps and get back to me. Don't discount the superior brass,20-ish less grains of powder,lower ES/SD,improved Terminal Effects,reduction in recoil,reduction in noise,vastly superior flight characteristcs and greatly increased relative FUNTITUDE. Hint.
Pardon my simply shooting all and then some,as you drool aloud. Hint.
Fhuqking LAUGHING!...............
