Speer
The Speer Impact .308 caliber 172 grain rifle bullet with Slipstream polymer tip is engineered for handloaders who want a hunting round that performs consistently from close range to extended distances. Built on Speer's proven molecular-bonding jacket technology, these bullets combine controlled expansion, deep penetration, and flat-shooting aerodynamics in a single offering. Whether you're developing loads for whitetail at 200 yards or pushing shots past 500, the Impact gives you the ballistic efficiency and terminal performance to do it without guesswork.
The Slipstream polymer tip is where the Impact separates itself from conventional designs. That aerodynamic nosecone reduces drag and boosts ballistic coefficient across the velocity spectrum, which means a flatter trajectory and less wind drift over distance. More importantly, the hollow-core construction under the tip triggers reliable expansion even when velocity dips below what most premium bullets require—a real advantage if your hunting ranges are mixed or your energy curves are steep. The molecularly fused jacket won't shed weight on impact, so your bullet stays together for deep, straight-line penetration.
Each box contains 50 rounds, making it ideal for load development, practice, or stocking your hunting ammunition supply. If you're already set up to reload .308, these bullets slot into a proven, straightforward handloading process. Precision and consistency start with quality components, and Speer's Impact delivers both.
| Caliber | .308 (7.62mm) |
| Bullet Weight | 172 grains |
| Bullet Style | Slipstream Polymer Tip, Hollow Core |
| Jacket Construction | Molecularly Bonded |
| Ballistic Coefficient G1 (3000–2500 fps) | .567 |
| Ballistic Coefficient G7 (3000–2500 fps) | .284 |
| Ballistic Coefficient G1 (2500–2000 fps) | .548 |
| Ballistic Coefficient G7 (2500–2000 fps) | .275 |
| Ballistic Coefficient G1 (2000–1500 fps) | .518 |
| Ballistic Coefficient G7 (2000–1500 fps) | .267 |
| Quantity Per Box | 50 rounds |
The Speer Impact 172 grain is compatible with any standard .308 Winchester rifle or magnum .308 platform that accepts .308-diameter bullets. Always consult your rifle's manual and perform pressure testing during load development.
Yes. The hollow-core Slipstream design initiates expansion at velocities 200 fps lower than comparable polymer-tip bullets, so you'll get consistent expansion even when velocity has dropped over distance. The high ballistic coefficient helps retain velocity downrange, supporting reliable terminal performance.
These are designed for hunting use. The controlled-expansion profile and deep penetration make them appropriate for medium to large game at a range of distances. The high ballistic coefficient and aerodynamic tip also support accuracy at extended ranges, making them versatile for mixed hunting scenarios.
Each box contains 50 Speer Impact .308 caliber 172 grain bullets ready for your handloading setup.
