Best ammunition brands for AR-15 deer hunting?

Caliber and Bullet Weight Selection

When choosing ammunition for AR-15 deer hunting, consider calibers such as 5.56x45mm or 6.5 Grendel, and bullet weights from 55 grains to 100 grains. For close-range shots, 55-62 grain bullets like Speer’s Gold Dot or Federal’s Premium Power-Shok are effective options. For longer shots, 77-100 grain bullets like Hornady’s ELD-X or 6.5 Grendel’s 90 grain InterBond provide greater accuracy and penetration.

Ammunition Types and Performance

When selecting ammunition, consider the type of hunting you’ll be doing. For dense woods or thick cover, opt for a heavier bullet with a higher BC (ballistic coefficient) like Hornady’s ELD-X or a more aerodynamic bullet like 6.5 Grendel’s 90 grain InterBond. For open-country hunting, a lighter bullet with less wind drift, such as Speer’s Gold Dot or Federal’s Premium Power-Shok, is a better choice.

Additional Considerations

Additionally, consider the twist rate of your barrel when selecting ammunition. A 1:8 or 1:9 twist rate is suitable for heavier bullets, while a 1:7 twist rate is better suited for lighter bullets. It’s also essential to practice with your chosen ammunition to ensure you’re comfortable with its performance and can make accurate shots.
