Which should be considered when sighting in a rifle?

• A. Gravity, air resistance and energy loss all have an effect on the bullet's trajectory
• B. The color of the stock
• C. The temperature of the barrel
• D. Wind direction only

Answer: (A)

When sighting in a rifle, the essential idea is to match the sights to the actual path the bullet will take once it leaves the muzzle. The bullet doesn’t travel in a straight line; gravity pulls it downward, and air resistance slows it as it flies. As the bullet loses energy from that drag, its velocity drops, which means more drop occurs over distance. Together, gravity, drag, and the resulting velocity loss shape the trajectory, so they determine where the bullet will strike at your chosen range. The color of the stock doesn’t affect the shot, and while wind can push the bullet sideways, it isn’t the only factor to consider. Barrel temperature can have a small effect through changes in velocity and barrel harmonics, but the primary things you must account for during sight-in are gravity, air resistance, and energy loss that influence the bullet’s drop.
