Hornady Unprimed Brass .300 AAC Blackout 50 ct (86751)

Description

If you're building .300 Blackout loads from the ground up, the brass is where everything starts, and Hornady treats it that way. These are new, unprimed cartridge cases in .300 AAC Blackout, packed 50 to the box and ready to prep, prime, and load. Hornady builds them with the same precision and attention to detail that made the company a leader in bullets and factory ammo, so what you're getting is a quality foundation rather than bulk commodity brass.

What Sets Hornady .300 Blackout Brass Apart

The big story here is consistency. Each case is measured for tight wall concentricity, which keeps the bullet seated straight in both the case and the chamber. That straight seating matters because it helps the bullet release uniformly on firing, and uniform release is what turns into predictable velocity and better accuracy downrange. Uniform wall thickness is a benchrest staple for a reason, and Hornady holds tight tolerances to keep every case in the batch pulling its weight.

Getting the Most From Your .300 AAC Blackout Reloading Brass

Consistent weight and internal capacity mean your powder charges behave the same way from case to case, which keeps pressures and velocities in a tight window across a loading session. Because the brass is made with greater care, you can typically expect more reloads per case before it's worn out, which stretches your component budget over the long haul. Every piece is hand-inspected, so you're starting with cases that are virtually identical to one another and dependable lot after lot.

One thing worth being clear on: this is a reloading component, not loaded ammunition. There's no primer and no powder, so you'll need to prime, charge, and seat a bullet before anything heads to the range. For anyone running a .300 Blackout AR or bolt gun and working up subsonic or supersonic loads, this is a solid brass to build on and tune to your rifle.
