The Sierra GameKing 6mm .243 90gr HPBT Tipped bullet is a reliable choice for reloaders pursuing medium-game hunting and varmint applications. Built on Sierra's proven match-grade engineering, this hollow-point boat-tail design combines consistent accuracy with controlled expansion. The 90-grain weight strikes a practical balance across modern .243 Winchester and 6mm cartridges, delivering the precision reloaders expect from Sierra while offering field performance tuned for hunting scenarios.
GameKing bullets are designed around a polymer-tipped hollow point that initiates rapid expansion on impact while the optimized jacket thickness helps manage penetration and weight retention. The boat-tail configuration enhances ballistic stability downrange, supporting flatter trajectories and tighter groups at distance. With published ballistic coefficients ranging from .320 to .490 depending on velocity, these projectiles maintain energy across a practical hunting envelope—from close-quarters shots to extended-range work where trajectory matters.
This is a 50-count box of reloading components, not loaded ammunition, giving handloaders the flexibility to tailor loads to their specific chamber, powder, and primer combinations. Whether you're working up precision hunting loads for a bolt gun or tuning an AR-platform 6mm build, the GameKing's balance of accuracy heritage and hunting-grade performance makes it a sensible choice for hunters who take their reloading seriously.
| Caliber | .243 inch (6mm) |
| Weight | 90 grains |
| Bullet Style | Hollow Point Boat Tail (HPBT) with Polymer Tip |
| Sectional Density | .218 |
| Ballistic Coefficient | .490 @ 2700 fps and above; .400 between 1380–2700 fps; .320 @ 1380 fps and below |
| Count | 50 bullets per box |
| Type | Reloading component (not loaded ammunition) |
The .243 inch diameter and 90-grain weight are compatible with cartridges like .243 Winchester, 6mm Remington, and other 6mm rifle chambers. Always consult your reloading manual to confirm safe load data for your specific rifle and powder combination.
These are reloading components only—50 unprimed, unpowdered bullets. You'll need to source brass, powder, and primers separately and follow published reloading data to assemble complete cartridges.
The polymer tip and hollow-point design are engineered to expand quickly upon impact, while the controlled jacket thickness helps the bullet penetrate effectively and retain weight. The boat-tail boat-tail boat-tail configuration provides the ballistic stability that supports consistent accuracy at hunting distances.
The BC varies with velocity: .490 at high velocity (2700+ fps) provides excellent downrange performance for extended-range shots, while the lower .320 coefficient at subsonic velocities reflects the bullet's behavior at closer ranges. This range of performance supports hunting across various distance scenarios where velocity naturally changes.
