Premium .45 ACP Brass – New & Once‑Fired Cases for Reloading

Reload reliable .45 ACP rounds with confidence using Diamond K Brass. We stock both new and once‑fired .45 ACP brass, hand‑sorted, tumble‑polished, and inspected to ensure consistent dimensions, smooth feeding in semi‑autos, and excellent reloadability. Ideal for range practice, competition, defensive loads, and commercial reloaders.

Why Choose Diamond K .45 ACP Brass

• Certified Quality: Every lot is checked for dents, splits, and primer‑pocket integrity before packaging.

• Large Pistol Primer: Cases are compatible with large pistol primers used in standard .45 ACP loads.

• Brass & Nickel Options: Choose traditional brass or nickel‑plated cases for corrosion resistance and smoother feeding.

• Tumble‑Polished & Cleaned: Once‑fired cases arrive free of range debris and ready for depriming, resizing, and loading.

• Mixed or Headstamp‑Sorted Lots: Available as mixed headstamp packs or headstamp‑sorted on request for collectors and specialty builds.

Benefits of Reloading .45 ACP Brass

Reloading .45 ACP brass saves money and gives you precise control over bullet selection and charge weights—perfect for high‑volume shooters and precision handloaders alike. Our processed once‑fired cases deliver near‑new performance at a fraction of the cost of factory‑loaded ammunition.
