Re: Wow, blundering around like freshly castrated cattle.
...then have a police marksman stick a 7.62mm round through it. If they can't pop a cap in the arse of a slow moving target against a light background then they should be handing back the firearms certification.
Oh dear. Firstly rifle sights aren't zeroed for use at high angles of inclination (or declination); secondly for sights to work the range must be known to a reasonable degree of accuracy; thirdly although the overall footprint of a drone might be quite large, there is actually a lot of empty space there - a lucky shot could be well inside the perimeter of the drone but still miss; fourthly where does the drone then (crash) land, and lastly where does the fired round finish up?
And of course if the drone is moving then getting a steady shot at a distance is (a) difficult and (b) likely to miss because the drone is moving at an unknown speed.
