Quick Answer
When choosing a hunting scope for a 6.5x55mm bolt-action rifle, look for high magnification power (12-24x), a large objective lens (44mm or larger), and a parallax adjustment mechanism with a large range of adjustment (20-60 yards).
Objective Lens and Field of View
For hunting 6.5x55mm caliber rifles, such as those used for Swedish moose hunts, a large objective lens (44mm or larger) is crucial for gathering as much available light as possible, especially during low-light conditions. This also enhances the field of view, making it easier to track and acquire targets. Look for scopes with a large exit pupil (around 4-5mm) to achieve this.
Focal Planes and First Focal Plane (FFP) Scopes
First focal plane (FFP) scopes offer a significant advantage for long-range shooting, as the reticle remains correct and proportional to the target at any magnification setting. When shopping for a 6.5x55mm rifle scope, consider a First Focal Plane (FFP) scope with a high zoom range (12-24x or 15-45x) and a precise reticle designed for hunting applications.
Parallax and Tracking
To ensure accurate shots, a scope should be able to eliminate parallax error across a wide range of distances (up to 60 yards or more). Look for scopes with a parallax adjustment mechanism that offers a sufficient range of adjustment and does not require the user to adjust the scope frequently. A good rule of thumb is to choose a scope with a parallax adjustment range of 20-60 yards.
