With our scope zeroed at 200 yards, we experimented with its LBR to determine the proper holdover marks for 300 and 400 yards. Though the reticle provided a total of 20 alternating dots and hashmarks below the central crosshair, the exercise proved much easier than expected, as the first dot was dead-on at 300 and the short hashmark under it produced point of impact about 2 1/2 inches low at 400. Granted, our test Hornady Superformance GMX 150-grain load has an extremely flat trajectory; nevertheless, our results suggest that the scope’s built-in corrections will cover nearly every practical long-range scenario.
Shooters who prefer to dial-in adjustments as targets are encountered may find the clicks a bit “soft,” and that a steady hand is needed to avoid overdialing under stress. Once adjustments are made, the turret knobs can be freed by loosening with a small hex wrench, and then rotated to the “0” setting.
The ER’s matte-black finish appears to be extremely tough and resisted ring imprints. The power-change control felt stiff but smooth and was well-marked. However, markings on the parallax-correction knob were limited to “50” and “∞” and did not provide incremental references.
Notwithstanding its design advantages and infallible mechanics, the ER’s true hallmark was its optical performance. Light transmission and edge-to-edge sharpness proved to be unsurpassed in comparison to other hunting scopes we have tested in this class. There was zero discernible distortion or color-fringing. Given Leica’s track record, we took on this evaluation with extremely high expectations, and by all appearances the company is finally in the riflescope business to stay.
