I've killed elk with rounds ranging from the 6mm Rem to .375 H&H, including a .270...and I can say without a doubt that a 150 speer hot-cor out of a .270 Win will straight up knock an elk's dick in the dirt.
I do dearly love my .340 Wby and how it puts elk down with authority with good bullets, but it also kicks the living $hit out of me.
