SIERRA BULLETS
The Sierra GameKing 100-grain 6mm spitzer boat tail bullet is built for hunters and reloaders who need reliable medium-game performance at extended ranges. With a heavy double-tapered jacket engineered for controlled expansion and deep penetration, this boat tail round shoots accurately and reliably in the 243 Winchester, 6mm Remington, and larger 6mm magnum cartridges. Where the flatbase Pro-Hunter works fine closer in, the GameKing's boat tail design pulls ahead when shots stretch past 300 yards—delivering the downrange stability and velocity retention that separate ethical long-range hunting from wishful thinking.
Reloaders appreciate GameKing bullets for their consistency and versatility. The 100-grain weight strikes a practical balance for the 6mm platform: heavy enough for elk-class medium game at reasonable ranges, yet light enough to push to hunting speeds without excessive powder. The spitzer profile cuts air cleanly, reducing drift and drop on longer shots. This bullet also earns respect in varmint hunting, especially when ranges push beyond typical close-range yardage where a lighter, faster bullet might be your first choice.
That said, GameKing 100-grainers aren't universal. The jacket design prioritizes penetration and expansion on living game—which is exactly why they perform poorly in handgun use at moderate velocities. If you're loading for silhouette competition or long-range rifle target work from standard-twist barrels, this bullet will deliver the accuracy you need. For field use on medium game from your rifle, the GameKing boat tail is the smarter pick than its flatbase sibling when distance is in the equation.
| Caliber | 6mm (.243) |
| Bullet Weight | 100 grains |
| Style | Spitzer Boat Tail |
| Jacket Type | Heavy Double-Tapered |
| Part Number | #1560 |
| Quantity | 100 bullets per box |
The Sierra GameKing 100-grain boat tail is designed for the 243 Winchester, 6mm Remington, and larger 6mm magnum cartridges. They perform in standard-twist barrels and deliver exceptional accuracy across these platforms.
If your hunting shots typically stay under 300 yards, the flatbase Pro-Hunter is a solid choice. Choose the GameKing boat tail when you expect to shoot beyond 300 yards—the improved ballistic coefficient means better downrange velocity and flatter trajectory where it counts.
No. The GameKing's jacket is too hard for handgun velocities and will not expand reliably on game at the moderate velocities achievable from pistol cartridges (except the largest wildcats).
Yes. The GameKing 100-grain bullet delivers outstanding accuracy in long-range rifle target and silhouette competition, making it a solid choice for shooters working with standard-twist barrels.
