Labrabaco v.0.7 released

The v = v + 0.1 of the “BC from Labradar tracks” calculator is here: The major change is noise filtering. Most people who have plotted Labradar tracks in spreadsheet software, must have seen occasional tracks of this shape: The tail of the graph — beyond 60 ms — is obvious noise; there is […]

How to mount a rifle scope on a Picatinny rail

In the shooting world, the process of mounting a rifle scope is surrounded by an esoteric halo that to me is absolutely inexplicable.

Motivations, intentions and disclaimers (brace for impact) This review has been written as a follow-up to this heated and particularly entertaining thread at Sniper’s Hide forums (UPD 2020: since that time, Sniper’s Hide moved back from to the original domain. As a result, all those moments will be lost in time, like tears in rain. But […]

Targets for printing

It all started because targets to print available for download on the Internet are mostly crap. Either they use perverse, archaic and totally unmetric units of measure, or they are in jpeg 30×30 px format, or they have vanity watermaks all around the page, or are dimensioned for some funny paper sizes, or — most […]
