John Linebaugh shot a 350 grain LBT .45 Colt traveling at 1187 fps through 42 inches of wet newspaper. The 338 Lapua 250 FXB traveling at 2900 fps managed 32". A 30-06 220 cor-lokt only made it through 17.5". Never underestimate the caliber that won the West.
I didn't bother looking into JHP rounds after reading the very same thing.
Every bullet has its place. Hard cast is not the be all end all.
