Sierra High Velocity Varminter Rifle Bullets .22 ca .224" 55 gr FMJBT 100/ct

Sierra High Velocity Varminter Rifle Bullets in .22 caliber, .224" diameter, 55 grain FMJBT are purpose-built projectiles designed to deliver consistent performance in semi-automatic rifles. Manufactured to replicate the ballistic profile of the military M193 cartridge, these full metal jacket boat tail bullets are engineered for use in AR-15, M16, and Ruger Mini-14 platforms. The 55-grain weight in the .224" specification provides a proven balance of velocity, energy retention, and trajectory stability across typical rifle engagement distances.

The full metal jacket construction with an exceptionally heavy jacket ensures reliable feeding and consistent bullet performance through semi-automatic platforms. A properly located cannelure enables secure case crimping, preventing bullet setback during chambering—critical for consistent velocity and accuracy across multiple rounds. The boat tail design reduces aerodynamic drag, supporting flatter trajectories and downrange energy maintenance. These specifications translate to reliable point-of-impact consistency and predictable terminal behavior, especially when loaded to medium velocities as specified for this bullet design.

Sierra's 55-grain .224" FMJBT excels in varmint applications where pelt preservation is a priority. The full metal jacket construction minimizes pellet fragmentation compared to hollow point designs, making this bullet selection ideal for fur-bearing small game at ranges typical of field hunting. Precision shooters and dedicated AR-15 handloaders value this bullet for training and load development where consistent ballistics and repeatable performance matter. The 100-count box format supports both single-batch handloaders and operators who run volume through their systems during range qualification cycles.
