Hornady's .300 PRC (Precision Rifle Cartridge), introduced in 2018, was purpose-built for long-range performance with high-BC bullets in a standard magnum-length action. Unlike the .300 Win Mag — which was designed decades before modern VLD and high-BC projectiles existed — the .300 PRC has a 30-degree shoulder, a generous freebore diameter, and a longer cartridge overall length that seats high-BC bullets well forward without compressing powder charges. The result is a cartridge that shoots flatter, bucks wind better, and reloads more efficiently than older .30-caliber magnums when paired with modern long-range bullets.

Understanding the .300 PRC Case

The .300 PRC is based on a modified .375 Ruger case, necked down to .30 caliber with a non-belted design. The absence of a belt — a feature on older magnums like the .300 Win Mag that was originally designed to headspace the cartridge — means the .300 PRC headspaces off the shoulder, just like a standard rifle cartridge. This produces more consistent headspace and longer brass life with proper sizing technique.

Case Prep Notes

  • Trim length: SAAMI trim-to length is 2.580 inches. Trim every 2–3 firings depending on your chamber.
  • Primer pocket: Large rifle magnum primers. Uniforming primer pockets on new brass adds consistency — recommended for precision loads.
  • Full-length vs. neck sizing: For bolt guns shot from a single chamber, neck sizing after the first firing extends brass life significantly. For hunting rifles that may be cycled under field conditions, full-length sizing ensures reliable chambering.
  • Shoulder bump: When full-length sizing, set the shoulder back 0.001–0.002 inches from fired case dimension for reliable feeding without excess headspace.

Bullet Selection for Hunting

The .300 PRC was engineered with high-BC bullets in mind. The following projectiles work exceptionally well for elk and mule deer at long range:

Top Hunting Bullets

  • Hornady ELD-X 212 gr (BC .673 G1): The cartridge's signature bullet and the one Hornady uses in factory loads. The 212-grain ELD-X shoots flat, retains velocity well past 600 yards, and the Heat Shield tip maintains BC better than older polymer tips. Excellent terminal performance on elk-sized game.
  • Berger Hybrid Hunter 205 gr (BC .640 G1): A bonded-style Hybrid design with outstanding accuracy potential. The 205-grain weight gives slightly more velocity than the 212s while maintaining excellent BC. A top choice for mule deer and antelope where flat trajectory matters.
  • Nosler AccuBond Long Range 210 gr (BC .730 G1): Bonded core with a polymer tip designed for long-range expansion. The high BC and bonded construction make this an exceptional elk bullet that holds together on heavy bone at any range.
  • Sierra Tipped MatchKing 220 gr (BC .640 G1): For hunters who prioritize accuracy and shoot at ranges where bullet expansion is less critical, the 220 TMK provides outstanding precision and excellent BC.

Powder Selection

The .300 PRC has a large case capacity — it needs slow-burning powders to reach full velocity without excessive pressure. The following powders perform best:

Recommended Powders

  • Hodgdon H1000: The gold standard for .300 PRC reloading. H1000 fills the case well, provides consistent velocities, and is temperature-stable enough for hunting use in variable conditions. Most load data shows 74–78 grains as the working range with 200–212 grain bullets.
  • Hodgdon Retumbo: Slightly slower than H1000, Retumbo can push velocities a few fps higher in some rifles. Can be finicky with temperature swings — best for summer/fall use in moderate climates.
  • IMR 8133: An Enduron series powder with excellent temperature stability — important for hunters chasing elk at dawn in 20°F cold after checking zero in 70°F heat. Slightly compressed charges are acceptable with this powder.
  • Hodgdon US869: An extremely slow-burning ball powder that works well in the .300 PRC's large case. Metered well through a powder measure for high-volume loading.

Starting Load Data (Always Verify with Current Reloading Manual)

Note: Always begin at minimum loads and work up. This data is for reference only — verify against current Hornady, Sierra, Nosler, or Hodgdon manuals before loading.

  • Hornady ELD-X 212 gr / H1000: Start: 73.0 gr | Max: 77.5 gr | Expected velocity: 2,800–2,920 fps (26" barrel)
  • Berger Hybrid Hunter 205 gr / H1000: Start: 74.0 gr | Max: 78.0 gr | Expected velocity: 2,850–2,960 fps
  • Nosler ABLR 210 gr / IMR 8133: Start: 76.0 gr | Max: 80.0 gr | Expected velocity: 2,820–2,900 fps

Primers: Federal 215 (Large Rifle Magnum) or CCI 250. Federal 215M (Match) for accuracy-critical loads.

OAL and Seating Depth

The .300 PRC's generous freebore allows long, high-BC bullets to be seated to magazine-length OAL without being jammed into the rifling. A SAAMI max OAL of 3.700 inches accommodates the 212 ELD-X seated at typical magazine depths in most rifles.

For best accuracy, find your rifle's lands with a bullet comparator and work back from there. Most .300 PRC rifles shoot best with bullets seated 0.020–0.040 inches from the lands, but magazine-length seating (typically 0.060–0.100 off lands with these long bullets) still produces excellent hunting accuracy — sub-MOA groups at 100 yards are routine.

Practical Ballistics: Why the .300 PRC Makes Sense for Western Hunting

With a 212 ELD-X at 2,860 fps, zeroed at 250 yards:

  • 300 yards: -2.5 inches
  • 400 yards: -10.2 inches
  • 500 yards: -23.8 inches
  • 600 yards: -44.1 inches
  • Retained energy at 500 yards: ~2,100 ft-lbs — more than adequate for elk

Wind drift at 500 yards in a 10 mph crosswind is approximately 13 inches — significantly less than the .300 Win Mag with comparable loads due to the higher-BC bullet selections the PRC accommodates at standard seating depths.

Brass Life and Cost Considerations

Hornady .300 PRC brass runs approximately $1.20–$1.50 per case. With proper prep and neck sizing, expect 5–8 loadings from hunting-velocity loads before primer pockets loosen. Full-length-sized cases used in field conditions typically run 4–6 loadings before retirement. At hunting load volumes (50–100 rounds per year), a batch of 100 cases will last most hunters several seasons.

Bottom Line

The .300 PRC represents genuinely modern cartridge design — engineered around the bullets and powders available today rather than retrofitted to accommodate them. For Oregon elk hunters who regularly deal with shots past 400 yards in open canyon country or eastern Oregon high desert, it's one of the best factory-supported cartridges available. The reloading component selection is straightforward, brass quality from Hornady is excellent, and the accuracy potential from a quality barrel is outstanding. If you're drawing elk tags in units where 500-yard shots aren't out of the question, this cartridge deserves serious consideration.
