300 PRC Brass

The 300 Precision Rifle Cartridge was engineered specifically for extreme long-range shooting and heavy .30-caliber bullets - competition pedigree built into every case design. Hornady, Lapua, Nosler, Norma, Peterson, and ADG all manufacture 300 PRC brass, providing reloaders with options across the full precision spectrum. If you’re building ammunition for the 300 PRC, match-grade brass from manufacturers like Lapua or Peterson directly rewards the accuracy potential this magnum cartridge was purpose-built to deliver on the firing line.

300 PRC Brass - Purpose-built for accuracy at distance

The 300 Precision Rifle Cartridge was designed specifically for extreme long-range competition and military adoption - a magnum built around the ballistics of modern heavy .30-cal projectiles. Driving a 230-grain projectile to roughly 2,950 fps, the 300 PRC bridges the performance gap between the .308 Winchester and the larger magnums, delivering ELR (Extreme Long Range) capability from a platform that still rewards shootable recoil and sensible barrel wear. The cartridge uses large rifle magnum primers, requiring careful component selection and attention to pressure management. For reloaders, this means that component quality - starting with premium brass - directly translates to accuracy, consistency, and case longevity.

300 PRC brass manufacturers and their strengths

The 300 PRC is newer than the .308 or 6.5 Creedmoor, which means availability is more selective than in established calibers. However, the major manufacturers serving competitive shooters have all stepped up with production. Here’s what each brings:

  • Hornady - The developer of 300 PRC, Hornady brass delivers predictable performance as the baseline for load development.
  • Lapua - Renowned for uniformity and extended case life. Top choice for serious long-range competitors.
  • Nosler - Premium brass engineered for precision and sub-half-MOA accuracy.
  • Norma - Known for tight tolerances. Performs exceptionally well in long-range competition rifles.
  • Peterson - Match-grade brass for sub-MOA accuracy and extended reload life.
  • ADG (Atlas Development Group) - Engineered for magnum pressures with controlled hardening for extended case life. Runs heavier; work loads up from ADG starting points.

Reloading and maintaining 300 PRC brass

The 300 PRC operates at magnum pressures - load development and component handling both demand precision. Large rifle magnum primers are mandatory; standard primers produce inconsistent ignition. With proper care, quality 300 PRC brass can handle five to ten reload cycles - premium cases from Lapua or ADG often extend beyond that. Annealing necks every few firings maintains consistent neck tension and delays failure, critical with magnums. Full-length sizing is standard, and inspecting the primer pocket for tightness catches wear early. Our guide to brass maintenance practices covers the full process from cleaning through storage and inspection.

Creedmoor Sports and precision reloading

Creedmoor Sports was founded by competitive shooters, and that background shapes everything we stock. The 300 PRC was designed by shooters, for shooters - and we stock brass from every major manufacturer because we know that building accurate ammunition for this cartridge demands component quality and consistency. Our team loads and shoots 300 PRC ammunition. If you’re building ammunition for extreme long-range competition or hunting, we can help you find the brass, bullets, and reloading components that match your precision requirements.
