Sierra 4625 Tipped GameKing .308 Win 125 gr, 100 Rounds

The Sierra 4625 Tipped GameKing .308 Win 125 gr bullets are engineered for hunters who demand reliable expansion and lethal performance across a range of velocities. These 100-round boxes deliver the accuracy Sierra is known for in a hunting-grade projectile designed to expand on impact while maintaining structural integrity. The polymer tip initiates rapid expansion through an open pocket that engages the lead core instantly upon impact, while the boat tail profile promotes stable flight and consistent accuracy downrange.

The 125-grain weight in .308 diameter makes these bullets a natural fit for .308 Winchester reloaders working up ammunition for medium to larger game. Sierra's tuned ogive geometry and boat tail configuration work together to produce an industry-leading ballistic coefficient, helping you hold velocity and energy at distance. The controlled jacket wall thickness ensures the bullet expands reliably without fragmenting prematurely, preserving penetration where it counts.

Whether you're working up precision hunting loads on your reloading bench or comparing bullets for a proven cartridge, these tipped GameKing projectiles give you the option to reload ammunition tailored to your rifle and hunting conditions. Each box contains 100 unprimed bullets—powder, primers, and brass are your responsibility—giving you the flexibility to assemble loads matched to your specific ballistics data and velocity targets.

Frequently Asked Questions

What caliber and rifle will these bullets work in?

These are .308 diameter, 125-grain bullets designed for reloading .308 Winchester ammunition. They are unprimed bullets only—you will need to supply your own brass, primers, and powder to complete loaded rounds.

What makes the polymer tip important for hunting?

The transparent green polymer tip serves two purposes: it initiates rapid expansion through an open pocket that engages the lead core instantly on impact, and it promotes aerodynamic uniformity for consistent ballistics. This design is intended to deliver quick expansion combined with controlled penetration.

How do these bullets perform at different shooting distances?

The ballistic coefficient varies slightly depending on velocity, with a BC of 0.318 at 2700 fps and above, 0.298 between 1400 and 2700 fps, and 0.287 at 1400 fps and below. The boat tail profile and tuned ogive help maintain velocity and energy downrange, supporting accuracy at extended distances.

Are these loaded rounds or unprimed bullets?

These are unprimed bullets only. Each box contains 100 bullets ready for your reloading press. You will need to provide brass, primers, and powder to assemble finished ammunition.
