    Subjective bad light test: 2xS&B vs. 1xKahlesK vs. Philippino Vortex vs. Chinese Vector

    In the recent years very decent optics got much more affordable. I have always been very conservative, as far as optics go -- bought expensive, proven models, and kept them for a long time.

    Range Report shooting uphill or downhill -- comparison of empiric methods of slope dope estimation

    How to hit your target at significant (> 10 degrees) uphill or downhill inclination without an electronic ballistic solver? We have all heard of the Rifleman's Rule and "equivalent horizontal distance". I have heard of it too, and took it for granted, until faced with a situation where the...

    Greetings from Switzerland (again)

    And here we go again: Yours truly, a shooter from Switzertland, mostly 300m rifle, but also anything else that goes bang. Relatively inexperienced at the long range game, I am here to learn and to share what I have learned. In advance I apologise for spelling, grammar and style -- English is...
