Description

Sierra 25cal 117gr Spitzer #1630

GameKing Bullets are developed for long-range hunting, which makes a significant difference in their extra leeway. GameKing bullets have a boat tail shape which generally brings ballistic benefits to hunters with matching target bullets. The 117 Grain GameKing delivers the same performance as the 25 Cal 100 Grain Pro-Hunter, but, it may be used in ranges between 200-500 metres.

FAQs

❓ Is this bullet suitable for hunting?

Yes—this is a dedicated hunting projectile, ideal for medium-sized game due to its weight and construction.

❓ What does “Spitzer Boat Tail” mean?

  • Spitzer: Pointed tip for improved aerodynamics
  • Boat Tail: Tapered base reducing drag and improving long-range performance

❓ How does it compare to lighter .25 cal bullets?

Heavier weight (117gr) offers:

  • Better penetration
  • Higher sectional density
  • Improved energy retention at distance

❓ Can it be used for target shooting?

Yes, but it’s optimized for hunting, not match-grade competition.

❓ What twist rate is recommended?

Most standard .25 calibre rifles (e.g., 1:10 twist) stabilize this bullet well, as commonly reported by reloaders.
