Underwood Ammo .45 ACP +P 255gr Hard Cast Flat Nose, 20-Round Box

Underwood Ammo .45 ACP +P 255-grain Hard Cast Flat Nose ammunition (brand part no. 727) loads a heavy, non-expanding bullet at +P pressure for shooters who need maximum penetration from a .45-caliber platform. Underwood Ammo casts the bullet from hardened lead alloy so the flat nose holds its shape through thick hide and heavy bone instead of mushrooming, a favorite among hikers and hunters who carry a .45 for protection against large animals. The +P pressure rating pushes the heavy bullet to higher velocity than standard-pressure .45 ACP, so only firearms rated for +P ammunition should fire it. Nickel-plated brass cases resist corrosion and feed reliably, rounding out a purpose-built deep-woods defense load.

Key Specifications

• The chambering is .45 ACP +P, a higher-pressure loading rated only for firearms marked as +P compatible.
• The bullet weighs 255 grains, well above standard .45 ACP weights for added momentum and penetration.
• The bullet is a hard cast flat nose, a hardened lead alloy that resists deforming on impact.
• Because it will not expand, the flat nose drives a deep, straight-line wound channel, built to punch through heavy hide and bone.
• Cases are made of nickel-plated brass, resisting corrosion and feeding smoothly through semi-auto actions.
• Each round costs about $1.37, reflecting the specialty heavyweight hard cast bullet.
• Each box holds 20 rounds, a practical quantity for a specialty deep-woods load.
• A full case packs 10 boxes for 200 rounds total, useful for shooters who carry this load regularly in bear country.
• At a shipping weight of about 1.03 pounds per box, the heavy bullets add noticeable heft over standard .45 ACP.

Frequently Asked Questions

Can I fire this in any .45 ACP pistol? No, +P ammunition generates higher pressure than standard .45 ACP and should only be fired in firearms rated by their manufacturer for +P loads.

Why choose a hard cast bullet over a hollow point? Hard cast flat nose bullets do not expand, so they drive deeper and hold together through thick hide and bone, which matters more than expansion for large-animal defense.

How many rounds come in a full case? A case contains 10 boxes of 20 rounds each, for 200 rounds total.
