Why? The 243 has a flatter trajectory and more enrgy then a 308win.
out to 500 yards as aA Navel & Military test have proven!The 243 was actually created by necking down a 7.62mm NATO case,a.30cal. or(308).[
(Winchester figures). The .243 is more lethal at 500 yards than the 5.56mm NATO (.223)or 7.62x39 (308) are at 200 yards!
I think most people realize that the 243 is a necked down 308. The article state that the 243 has more nockdown power than the 223 and 7.62x39 (not the .308) the 308 is the 7.62x51 and not a 7.62x39.Im pretty sure the 243 isnt more lethal than a 308
