Sierra 4680 Tipped GameKing .308 Win 180 gr - 100 Rounds Per Box

The Sierra 4680 Tipped GameKing .308 Win 180 gr bullet combines proven hunting performance with the precision foundation Sierra built into their match-grade designs. Loaded in 100-round boxes, these reloading bullets are engineered for hunters and handloaders who demand both accuracy and lethal expansion at variable hunting ranges. The 180-grain weight in .308 diameter strikes a balance popular with medium to large game hunters working with standard rifle platforms.

Sierra's approach here merges their legacy of ballistic accuracy with controlled expansion through a polymer-tipped design. The transparent green tip promotes uniform ballistics and initiates rapid expansion on impact, while the boat-tail profile supports stable flight and tighter shot groups downrange. The optimized jacket wall thickness manages expansion rates across the velocity spectrum, helping the bullet penetrate effectively without fragmenting prematurely—a critical trait when hunting at distances where velocity varies significantly.

These are components only, not loaded ammunition, giving you full control over powder charge, primer selection, and case preparation to match your rifle's characteristics and your specific hunting application. The 4680's sectional density of 0.271 and ballistic coefficient data across velocity ranges (.515 at 2100 fps and above, .480 between 1680–2100 fps, and .445 below 1680 fps) provide the technical foundation for load development and trajectory prediction at extended distances.

Frequently Asked Questions

What rifles can I use Sierra 4680 Tipped GameKing bullets with?

These .308 diameter, 180-grain bullets are designed for .308 Winchester and other cartridges that accept .308 projectiles. Always verify compatibility with your specific rifle and consult published load data before reloading.

Are these loaded rounds or reloading components?

The Sierra 4680 Tipped GameKing are reloading components only—bullets, not finished ammunition. You'll need to prepare cases, seat primers, add powder, and insert the bullet yourself using proper reloading equipment and published load data.

How do the ballistic coefficients change with velocity?

Sierra provides three BC values depending on impact velocity: 0.515 at 2100 fps and above, 0.480 between 1680 and 2100 fps, and 0.445 at 1680 fps and below. These account for how the polymer tip and bullet design perform across the velocity spectrum, helpful for trajectory calculation at different ranges.

Is the Sierra 4680 suitable for hunting?

Yes, the polymer-tipped design and controlled expansion characteristics are intended for hunting applications. The 180-grain weight is commonly used for medium to large game. Follow all local hunting regulations and use appropriate load data for your intended application.
