Alpha Munitions 25 GT Rifle Brass 100ct Unprimed OCD

Description

Alpha Munitions has carved out a reputation as one of the best brass makers in the country, and the 25 GT is a prime example of why. This case is built on the 6mm GT platform necked up to .257 caliber, slotting neatly between the 6 GT and the 6.5 Creedmoor. The result is a cartridge that lets you launch heavy, high-BC quarter-bore bullets at moderate velocities with lighter recoil than a 6.5, which is exactly what competitive shooters have been chasing. Every case runs small rifle primers and ships unprimed, ready for your own load development.

What Sets the 25 GT Brass Apart

The headline feature here is Alpha's OCD, or Optimized Case Design, with its optimized case head technology. This is engineered to stretch primer pocket life and overall case longevity, even when you're running at the higher pressures and velocities that precision loads demand. Alpha builds everything at their facility in Salt Lake City and inspects every piece on their own in-house system, so you're not dealing with graded lots or factory seconds. That kind of consistency is what keeps your SDs and ES numbers tight across a long string.

Why Reloaders Reach for 25 GT Brass

The 25 GT has quietly become a real player on the PRS and NRL circuits, with top-ranked competitors using it to push bullets like the Berger 135 LRHT and Hornady 134 ELD-M right in the 2,700 fps neighborhood. It feeds cleanly from AICS magazines thanks to the GT case geometry, no spacers or lip tweaks required. Popular powders like Varget and H4350 fall right in the sweet spot for this case capacity. It's also drawing interest from hunters who want a flat-shooting quarter bore that handles the heavier .257 projectiles.

If you're setting up a 25 GT and want brass that holds up to repeated firings and keeps your velocities honest, this is about as good as it gets. Grab your dies, your powder of choice, and start working up a load.
