Sierra GameKing 25 Cal 90 Grain HPBT Bullets (Box of 100)$39.28
Availability: In Stock
The Sierra GameKing 22 Cal 55gr HPBT bullets are a time-tested choice for reloaders working with .22 centerfire rifles who want reliable expansion and consistent accuracy. These hollow point boat tail projectiles have been delivering field-proven performance since 1984, earning their place in countless handloads for varmint hunting and target shooting. The 55-grain weight and open hollow point design are engineered to expand predictably on impact, making them especially effective on small game and varmints where rapid energy transfer matters. A full box of 100 gives you plenty to work with for load development and extended range sessions.
What makes the GameKing stand out is the combination of Sierra's proven high-velocity construction with accuracy potential that rivals match-grade ammunition. Reloaders consistently report that these bullets shoot tight groups across a variety of .22 centerfire platforms—from the ubiquitous .223 Remington to other standard .22 center cases. The boat tail design helps maintain velocity and trajectory at distance, which is particularly valuable when you're stretching shots in varmint hunting or precision rifle work.
The large, open hollow point cavity is engineered to initiate expansion reliably across the velocity ranges typical of .22 centerfire rifles. That same design makes the GameKing suitable for handgun applications in .223 Remington and larger .22 centerfire handgun cartridges if you reload for that niche. The only limitation is in very tight cases where bullet mass outpaces case capacity—a non-issue for standard cartridges and most handloads.
| Caliber | .22 (0.224" diameter) |
| Weight | 55 grains |
| Bullet Type | Hollow Point Boat Tail (HPBT) |
| Sierra Part Number | #1390 |
| Sectional Density | 0.157 |
| Ballistic Coefficient | 0.185 @ 2800 fps and above; 0.189 between 2800–1800 fps; 0.193 @ 1800 fps and below |
| Box Count | 100 bullets |
| Introduction | 1984 |
The Sierra GameKing 55gr HPBT works across standard .22 centerfire rifle cartridges. Sierra notes they are compatible with most .22 centerfire cases; the only exception is very small cases where the 55-grain bullet weight would exceed safe case capacity and muzzle velocity limits. The .223 Remington and similar standard .22 centerfire rifle cartridges are ideal applications.
Yes. Sierra specifically mentions that the GameKing 55gr HPBT is suitable for short-range varmint shooting in handguns chambered in .223 Remington or larger .22 centerfire handgun cartridges.
Sierra engineers the GameKing for high accuracy potential. Reloaders often report match-grade accuracy from these bullets in rifles, though actual performance depends on your specific rifle, load development, and handloading precision. They are not a premium match-only line, but rather general-purpose varmint and small-game bullets with proven accuracy.
The 55-grain GameKing has a sectional density of 0.157. Ballistic coefficient varies with velocity: 0.185 at 2800 fps and above, 0.189 between 2800 and 1800 fps, and 0.193 at 1800 fps and below. These coefficients reflect the boat tail design's effect on drag across typical velocity ranges.
