Sierra 1390 GameKing 22 Cal 55gr Hollow Point Boat Tail Reloading Bullets - 100/Box

The Sierra 1390 GameKing is a .22 caliber (.224" diameter) rifle reloading bullet engineered for long-range hunting applications. Featuring a 55 grain weight and a Hollow Point Boat Tail (HPBT) design, the GameKing gives reloaders the ballistic advantage of a boat tail base combined with the proven terminal performance of a hollow point tip.

Each bullet is built around a traditional lead core wrapped in a precision copper jacket, with no cannelure for a smooth, uninterrupted profile that promotes consistent accuracy. The boat tail design reduces drag and improves the ballistic coefficient, helping the bullet retain velocity and energy downrange, while the hollow point initiates reliable expansion on impact. Sierra builds the GameKing specifically for hunting at extended ranges where trajectory, wind-bucking ability, and consistent terminal performance matter.

With a sectional density of .157, the 55 grain GameKing is well suited for .22 caliber varmint and predator hunting loads. Each box contains 100 bullets, ready for the reloading bench.
