Sierra 22 Cal 45gr SPT

The Sierra 22 Cal 45gr SPT is a high-performance component bullet designed for handloaders focused on varmint hunting, target shooting, and pest control in .22-caliber platforms. As part of Sierra’s Sports Master lineup, this .224‑inch, 45‑grain soft-point bullet offers controlled expansion, dramatic terminal performance, and precise accuracy at high velocities.

Featuring a soft-point exposed lead core and tapered jacket, the 22 Cal 45gr SPT initiates immediate expansion upon impact, producing wide wound channels and limiting over-penetration—ideal for coyotes, prairie dogs, and other small varmints. The round-nose profile ensures reliable feeding in bolt-action and semi-auto rifles commonly chambered for .223 Remington and 22-250 Remington.

Manufactured to tight component tolerances—45.0 grains weight, 0.224″ diameter, approximately 0.930″ overall length, and a sectional density near 0.126—the bullet maintains uniform jacket thickness, concentric alignment, and consistent meplat. These quality characteristics promote repeatable accuracy and reliable chambering in tubular magazines and bolt-rifles.

Optimized for rifles with twist rates between 1:12 and 1:14, the 45gr SPT performs best at velocities from 3,000 to 3,500 fps. Shooters report exceptional expansion and consistent terminal effect on small game at distances up to 300 yards, combining explosive impact with high accuracy.

As a component bullet, the Sierra 22 Cal 45gr SPT gives reloaders full control over powder, primer, and seating depth—facilitating tailored load development for specific recoil, trajectory, and terminal performance. It is not factory-loaded ammunition but a premium soft-point component for shooters seeking explosive varmint performance with reloader customization.

In summary, the Sierra 22 Cal 45gr SPT is a top-tier soft-point bullet offering rapid expansion, precise shot placement, and handloader flexibility. Ideal for varmint control, target work, and small-game pursuits, this 45gr SPT delivers consistent, high-velocity terminal performance in .22-caliber platforms.
