Blaser B2 2.5-15×56 iC Riflescope Review

My range analyses evolved over the years, mainly through mentoring by friends who review many more firearms than I do. However, one aspect I add that many reviewers don’t is the collection of detailed data. This isn’t because I’m smarter somehow; it’s because I am a research scientist, and data collection is lesson number 1 in our training. The type of range analyses I run, and the manner of data collected, are, however, because people like editor, Dan Zimmerman, taught me the details of a ‘Box Test’ for riflescopes, and the owner of 4StableSticks, Lilian Camalet, introduced me to their wonderful fieldrests. I’ll provide additional details of the range workup in a separate review of the Blaser R8 rifle. Still, for the Blaser B2, both the accuracy and Box Test data give an indication of how the riflescope x rifle combination performed.

I mentioned in an earlier set of reviews – of a Meopta riflescope and Mauser rifle – of a morning at the range blanketed with thick fog. The fog limited visibility, but because of meetings, I had limited time to collect data. This was a tough test for both riflescopes and shooter’s eyes, with the further targets (300 and 400 yards) nearly invisible through the white haze. That adds a good deal of weight to the accuracy estimates. The first observation is that all groups, at all distances – off the bench or 4StableSticks Ultimate Carbon, Standing model fieldrest) – were less than 1 x MOA, with five of the seven groups less than 0.5 MOA. As a reminder, the diameter of 1 x MOA groups is approximately 1, 2, 3, and 4 inches at 100, 200, 300, and 400 yards, respectively. The clarity and brightness of the B2 provided the needed resolution for very accurate shooting, even out at the distances significantly affected by the thick fog. At the time, I was less than happy with the environment, but in retrospect, the fog was a fortunate intruder.
