Underwood .475 Linebaugh 300 grain Xtreme Penetrator ammunition is engineered for shooters who demand maximum penetration and straight-line performance from a powerful revolver cartridge. Designed around a solid fluted projectile, this load delivers deep penetration and consistent performance in heavy-duty hunting or defense applications.

The 300 grain Xtreme Penetrator bullet is machined from solid copper and features a precision fluted design that promotes fluid displacement and straight, controlled penetration without relying on traditional expansion.
