Underwood Ammo 728 45ACP 255gr Hard Cast Flat Nose 20 Per Box/10 Case

Underwood Ammo 728 is a 45 ACP hard cast flat nose round built for serious shooters and hunters who demand reliable, heavy-hitting performance. At 255 grains, this projectile brings real stopping power and penetration to your 1911 or service pistol, whether you're working on accuracy at the range, hunting medium game, or training for self-defense. The hard cast bullet construction resists deformation and delivers consistent performance through barriers and heavy clothing—no expansion unpredictability, just straightforward energy transfer and deep, reliable penetration.

Underwood loads these rounds to full power, so you get the velocity and momentum that flat nose geometry was designed for. Hard cast bullets are also gentler on barrel wear than some premium hollow points, making them smart practice and duty ammo for high-volume shooters. Whether you're running suppressed loads through a PCC or pushing full velocity in your carry gun, the flat nose profile feeds reliably in a wide range of platforms and magazines.

This case pack includes 200 rounds total—ten boxes of 20—so you can stock up for extended range sessions, hunting trips, or serious practice without reordering constantly. Underwood's quality control and consistent loading mean you'll get the same point-of-aim and recoil shot after shot, which matters when you're dialing in a load or trusting your ammo in the field.

Frequently Asked Questions

Will this ammunition work in my 1911 or duty pistol?

Yes. Underwood 728 is loaded for the 45 ACP cartridge and is compatible with any standard 45 ACP firearm, including 1911s, Glock 21s, and other service pistols. The flat nose profile feeds reliably in most magazines, though you should always function-test a new load in your specific gun before relying on it.

What's the difference between hard cast and hollow point ammunition?

Hard cast bullets are designed to penetrate deeply and resist deformation, making them ideal for barriers, tough game, or situations where reliable deep penetration matters more than expansion. Hollow points expand on impact, which can limit penetration but increase wound trauma. Underwood's hard cast approach prioritizes straight-line performance and barrier penetration.

How many rounds are in a case?

Each case contains 200 rounds—ten boxes of 20 rounds each. This bulk packaging is convenient for serious range training, hunting seasons, or shooters who move a lot of ammo regularly.

Is this ammunition suitable for hunting?

The 255-grain hard cast flat nose is capable of hunting applications where deep penetration and reliable performance are priorities. However, always verify that your intended quarry and hunting regulations permit hard cast ammunition, and choose a load appropriate for your game and distance.
