45 ACP Brass Casings

Owners of 1911s and other .45 ACP pistols often handload their own ammunition due to the relatively high cost of loaded ammo. Reloading with 45 ACP brass casings also allows you to fine-tune his or her cartridges to suit various needs.

.45 ACP brass typically uses large pistol primers, though some manufacturers use cases that accept small primers. Don't waste time picking cases off the ground and checking them individually--grab some our affordable, professionally processed brass!

Quality casings can be had from Jagemann, Top Brass, and other companies.

  1. Starline 45 ACP +P New Unprimed Brass Casings - 100 Casings


    In stock

    Manufacturer SKU 1520
    This is not loaded ammunition. These are component cases, which are useless unless you know how to load them with bullets, powder and Boxer primers.

    When you want to load your own overpressure ammo, don’t count on the old brass you find lying on the ground. A great 45 ACP +P load deserves a great 45 ACP +P case. Starline satisfies.

    This case doesn’t just make it easier to identify your 45 ACP +P thanks to its special headstamp. It is a strengthened version of Starline’s already strong 45 ACP case, with a thicker web and heavier sidewall that help contain all that added chamber pressure. The fortified case does have about two fewer grains of internal water capacity than a standard 45 ACP case, so pour accordingly. 0.892 - 0.897" OAL

    Starline is a family-owned business, headquartered just down the road from Sierra Bullets in Sedalia, MO. That’s as American-made as it gets in our book.

    In stock

    Manufacturer Winchester
    Ammo Caliber 45 ACP (Auto)
    Manufacturer SKU U45ACP
    Quantity 100
    This is not loaded ammunition. These are component cases only – i.e. just the brass shells that handloaders use to make their own handgun cartridges.

    No more will you scurry across the ground at the pistol range, torturing your poor lower back as you scour the earth for empty 45 ACP cases. You have ascended. You’re getting your next batch of brass factory direct, because you want your next batch of 1911 ammo to be your best to date.

    This is the same brass Winchester uses to load their own fine ammo. Each case is drawn and cut in accordance with exact tolerances, thus assuring smooth feeding and dependable chambering in any .45 cal firearm in your collection.

    These cases aren’t primed. You’ll have to bring all three other major components to the table when you load them. Check out our 45 ACP bullets so long as you’re here!
