The Sierra GameKing 55-grain .22 caliber FMJ boat tail bullet is a serious choice for reloaders who need a proven, military-profile round for AR-15s, M16s, Ruger Mini-14s, and other semi-automatic .22 centerfire rifles. Designed to replicate the ballistics of the M193 military cartridge, this full metal jacket boat tail delivers consistent performance across a wide velocity range—and it's equally at home in .22 centerfire handguns where pelt preservation matters. The cannelure is positioned for reliable crimping and positive feeding, and the exceptionally heavy jacket ensures predictable performance whether you're loading for medium-velocity varmint work or general-purpose shooting.
If you reload for varmint hunting where you want to minimize pelt damage, these bullets reward medium-velocity loads with clean, non-expanding performance. The boat tail design supports consistent ballistics downrange, and the sectional density (.157) keeps energy transfer manageable in small game. Reloaders value GameKing bullets for their quality construction and track record; Sierra has been refining this design since its 1985 introduction, and it remains a workhorse for precision handloaders who refuse to compromise on consistency.
You get 100 bullets per box—enough to develop loads, test accuracy, or stock your bench for a serious reloading session. Whether you're tuning an AR platform, working up loads for a Mini-14, or loading for a .22 centerfire handgun, these FMJ boat tail rounds give you a baseline of reliability and performance you can build on.
| Caliber | .22 (0.224") |
| Weight | 55 grains |
| Bullet Type | Full Metal Jacket Boat Tail |
| Sectional Density | 0.157 |
| Ballistic Coefficient (3000+ fps) | 0.272 |
| Ballistic Coefficient (2400–3000 fps) | 0.245 |
| Ballistic Coefficient (below 2400 fps) | 0.235 |
| Box Count | 100 |
These 55-grain Sierra GameKing bullets are specifically designed for semi-automatic .22 centerfire rifles like the AR-15, M16, and Ruger Mini-14. They replicate the ballistics of the military M193 round and are equally suitable for .22 centerfire handguns.
They're excellent for varmint and small-game hunting where pelt preservation is important. Because they're non-expanding full metal jacket bullets, they minimize damage to hides and meat when loaded to medium velocities. They're also a solid general-purpose practice and training round.
For varmint hunting and pelt preservation, load to medium velocities. In handguns, medium handgun velocities are recommended to prevent tumbling on impact. The ballistic coefficients vary across the velocity spectrum: 0.272 at 3000 fps and above, 0.245 between 2400–3000 fps, and 0.235 below 2400 fps.
Each box contains 100 bullets, giving you a solid quantity for load development, practice, or stocking your reloading bench.
