Frequently Asked Questions

What is the advantage of the 300 PRC cartridge over the 300 Win Mag?

The 300 PRC offers superior factory-standardized accuracy due to its high-performance geometry, including fast twist rates and optimized bullet seating. This ensures consistent performance across various rifles, whereas the 300 Win Mag is more tailored for handloaders who can manipulate bullet seating depth.

What are the key differences between Hornady's ELD-X and CX bullets?

The ELD-X is a versatile hunting bullet with match-grade accuracy and reliable expansion down to 1600 fps. The CX is a monolithic bullet designed for deep penetration, heavy bone impacts, and use in lead-restricted areas, prioritizing terminal energy transfer.

Why does Hornady prefer 30-degree shoulder angles for cartridges like the 7mm PRC?

Hornady uses 30-degree shoulder angles for manufacturing reliability and to prevent 'hunched shoulders' during high-volume production. This design choice ensures consistent brass formation and feeding, unlike steeper angles that might be preferred by some handloaders for brass trimming.

What accuracy standard does Hornady aim for with its A-TIP bullets?

Hornady sets stringent accuracy standards for its A-TIP bullets, aiming for sub-half MOA (approximately 6-7 tenths of an inch) for 10-shot groups at 200 yards, showcasing their commitment to extreme precision for competition and long-range shooting.
