.17 Mach IV (Berger Bullets Data)

The .17 Mach IV, built on the .221 Fireball case necked down to accept .172-inch projectiles, is a favorite among varmint hunters and precision shooters seeking flat trajectories and explosive terminal performance. When paired with Berger bullets — known for their exceptional consistency and match-grade construction — the cartridge’s potential is fully realized.

Berger offers a selection of lightweight .17-caliber bullets that cater perfectly to the Mach IV’s characteristics. From 15- to 25-grain variants, each bullet is designed with a focus on high ballistic coefficients, uniformity, and reliable expansion. This makes them ideal for both benchrest-level precision and practical field performance on small game.

Handloaders who select Berger bullets for the .17 Mach IV often note tight groupings at 100 yards and beyond, as well as explosive on-target effects — a direct result of Berger’s controlled expansion and weight-forward design. In varmint applications, this translates to clean, effective hits with minimal pelt damage when desired.

The synergy between Berger’s premium bullet designs and the Mach IV’s high-velocity nature allows reloaders to craft highly effective, custom-tuned rounds. Whether using the cartridge in a custom bolt-action rifle or a converted single-shot platform, Berger bullets help deliver the performance edge that precision-minded shooters seek.
