Underwood Ammo 454 Casull 360gr Hard Cast
Underwood Ammo 454 Casull 360gr Hard Cast stands out as the market leader for maximum kinetic energy in hard-cast revolver loads, delivering the highest straight-line power and momentum of this list for serious hunting or penetrative applications. It is more expensive on a per-round basis and produces heavier recoil than the 44 Mag options, but for buyers prioritizing absolute terminal performance over soft-shooting practicality it outpaces the others technically and financially by reducing the number of rounds required in big-game scenarios.
