    Labrabaco: a G7 BC calculator from Labradar tracks

    A beautiful rig indeed! Surprisingly comfortable to shoot (but the blast coming to the spotter feels like peeling off eye retina and cracking the dental enamel). A friend of mine has acquired one recently, and is trying to develop a 375CT load with custom solid bullets. These to seem to fly...

    Labrabaco: a G7 BC calculator from Labradar tracks

    While we're off-topic, did you have a chance to compare the PVM-08 output with velocity measurements given by shotmarker? I was always wondering what the former is worth in terms of velocity measurements.

    How does it match the published BCs?

    Labrabaco: a G7 BC calculator from Labradar tracks

    Good! Let me know how it goes. Btw, your data looks very regular; looks like a perfect range to run Labradar measurements.

    Labrabaco: a G7 BC calculator from Labradar tracks

    Yes, it is possible. Yes, it does work. I have put together some code to calculate G7 ballistic coefficients from Labradar tracks. The tool is available here: https://bc.geladen.ch/labrabaco/labrabaco.html It all runs in your browser...

    Labrabaco: a G7 BC calculator from Labradar tracks

    There is a know bug (corrected in the yet-to-be-released version) -- the system fails, in exactly the way you have described, when the distance unit is set to feet. Would that be the case?

    Dope shooting uphill - tell me why I'm wrong

    +1. In [pretty extreme] alpine terrain, most shots do not exceed ±20° LoS elevation. If I remember well, the steepest shot I ever had to take was -33°.

    Dope shooting uphill - tell me why I'm wrong

    1. Any smaprtphone with Android or iOS, and the ballistic calculator app which has the user interface that you like best (they all do the same, to a rounding error close). My personal preference goes to calculators which understand and use publicly available Doppler-measured curves -- Lapua 6DOF...

    Dope shooting uphill - tell me why I'm wrong

    As far as battery-free solution go, nowadays I just put the angle of sight adjustments directly in the rangecards, e.g. https://k31.ch/wp-content/uploads/2021/10/rangecards-k31-xxi-easy-v7.pdf Improved rifleman's (eventually with the EBRR clicks) is ok for an occasional shot. But if the angle...

    Dope shooting uphill - tell me why I'm wrong

    Rifleman's rule is total crap. "Improved" works way better, but depends on zero distance. cf. https://geladen.ch/en/inclined-fire/

    Sorry, I don't understand what you mean.

    Labrabaco: a G7 BC calculator from Labradar tracks

    That's what Labradar devices are built for; it's built into the system, no need for additional software.

    Labrabaco: a G7 BC calculator from Labradar tracks

    I have a beta running, with much more precise calculations (I could get my hands on fairly large volumes of data from a non-EU-castrated box, which helps). The new version does a much better job in making sense out of noisy data. As of yet, however, it holds on shoestrings and is not polished...

    Swiss K31: Stunning

    Back in the old days, when Facebook did not yet grow into the monster which ate us all, a few people on a French-speaking Swiss guns forum have tried that: https://www.feulibre.com/t11247p50-beavertail-pour-un-p210 (see also the following pages, there are bits of STL available for download, if...

    Swiss K31: Stunning

    Wyss Waffen in Switzerland, Karl Nill in Germany (and a few others) used to manufacture add-on beavertails, just to fix this. There are two kinds: one with a hole, for the screw which holds the trigger group on -6 models, and the plain one, which goes on military -2 models (which you seem to...

    Rifle Scopes Vector Optics 34mm Continental 5-30x56mm FFP with VCT-20 Reticle

    I have one of these – the Vector Continental 34 mm 3-18x50 FFP – for about a year now. I will start by saying – this is dramatically better than all I have seen from China before. Bought it because (1) I do not have $$$ to equip all my rifles with S&B or Kahles and (2) because I like pain an...

    Sako S20 Optilock 20 MOA mount: review

    After the initial joy of owning a magnificent new Sako S20 rifle, comes the awkward "I should have taken a Tikka" moment – this is when the new owner inspects the optics mounting rails. There is a problem with the original bits of picatinny in front and behind the ejection port. Actually, three...

    Labrabaco: a G7 BC calculator from Labradar tracks

    Version 0.6 is coming soon -- I have collected some 350+ recorded tracks (last Wednesday was intense! -- 10 different guns, 7 different projectiles), and have a few ideas on how to get more precision out of less data. Stay tuned.
