Underwood 454 Casull 360gr Wide Nose Gas Check Hard Cast Ammunition

Underwood Ammo’s 454 Casull load (part no. 738) fires a heavy 360 grain Wide Nose Gas Check hard cast bullet finished in Underwood’s Black Cherry coating, a purpose-built deep-penetration round rather than an expanding defensive load. Underwood Ammo‘s hard cast bullets are built as solids that drive straight through heavy muscle and bone rather than mushrooming, and the Black Cherry coating is a polymer-based compound whose thermal stability lets it handle more heat and pressure than Underwood’s earlier Hi-Tek coating. The coating protects against gas cutting with strong wear and abrasion resistance, and it prevents lead-to-bore contact, virtually eliminating lead fouling in the barrel.
