A Bushnell 6-18x40mm Rimfire scope proved to be a perfect match for the new Savage rifle. It has a matte-finished, one-inch tube, weighs a hair over 21 ounces and is 13.75 inches long. Hundred-yard field of view ranges from 18 inches at 6X to 5.5 inches at 18X.
A five-inch tube length offers plenty of ring spacing latitude for most rimfire-size receivers. It has multi-coated lenses, binocular-style focusing and side-mounted parallax adjustment ranging from 10 yards to infinity.
The Bushnell 6-18x40mm windage and elevation adjustment range for the second focal plane-located Multi-X reticle is 80 inches at 100 yards in quarter-minute clicks. Eye relief in some variable-power scopes varies as magnification is changed, but in the Bushnell, it remains a constant five inches over its entire adjustment range.
In addition to standard windage and elevation adjustment dials with quarter-minute graduations, Bullet Drop Compensating dials for the .22 Long Rifle and .17 HMR cartridges are included. Here’s how they work.
After the rifle has been zeroed dead-on at 25 yards with the standard elevation dial installed, it is replaced by the .17 HMR dial while making sure its 25-yard mark is aligned with the index mark on the body of the scope. Primary markings on that dial are in 25-yard increments out to 300 yards.
In other words, if your trusty laser rangefinder indicates 175 yards to that unsuspecting flickertail, simply spin the dial to 175, hold the crosshairs dead-on, squeeze the trigger and watch the little varmint bite the dust.
For a rifle in .22 LR, the rifle is first zeroed at 75 yards with the standard dial. The standard dial is then replaced with the .22 LR dial with its 75-yard mark in alignment with the index mark on the scope.
The Bushnell 6-18x40mm primary range markings are also in 25 – yard increments but only out to 150 yards. Smaller marks between the primary markings of the .22 LR and .17 HMR dials allow fine-tuning for in-between distances and for differences in the trajectories of various loads.
The BDC system proved to be quite accurate. After using the standard dial to zero the CCI A17 load dead-on at 25 yards, I switched to the .17 HMR dial and fired groups at 100, 150, 200 and 250 yards with the dial adjusted for those distances.
Points of impact of all groups would have been inside the dimensions of a prairie dog, although I don’t consider the .17 HMR a consistently reliable killer on those critters at much over 200 yards.
