I would stress that my rifle / pellet / scope combination is awesomely accurate, there was zero wind so deviation wasn't an issue horizontally for a wounding shot and, clearly, I took a good amount of time for it. But it is an absolutely maximum distance under ideal conditions. Oddly enough, I'm more confident up to that distance with the HW100 than with the FAC, the Weihrauch is that good.
Here is the rifle -- which has been tuned for further consistency and shot-count:
For the geeks amongst us, at 48 yards the pellet is travelling at 570fps with a retained energy value of 7.3 ft
