For long‑range, pick a bullet that has a high ballistic coefficient but isn’t too heavy to choke the barrel. In practice that means something like a 147–155 grain round for a 7.62 or a 150–160 grain for a .308, firing around 2,800–3,100 fps. The weight keeps drag low, while the velocity keeps the trajectory flat enough that wind drift stays manageable. If you go too light you’ll get too much drop; if you go too heavy you lose velocity and energy over distance. Aim for that middle ground where the bullet stays in the air long enough to hit your target with a tight group.

The wind’s light, just a couple of knots from the east. No major drift to worry about, but keep the scope up if you’re firing beyond 800 meters.

Sounds good. Keep that picture steady, wait for the breath to settle, and fire when the scope reads the exact point. No room for error.
