    Can't argue with your personal experience...but it's far from being true and actually sounds quite weird. Links have been changed. On the other hand, just drop them an email (check the page contact form or try [email protected]) and that's it. I've been running Patagonia for many...

    Precision Rifle Gear Garmin Xero C1 - It really is that good (Take 2!)

    Here is an online tool to convert FIT files to Excel https://www.fromfittoxlsx.com/ Just out of curiosity, what would be the real reason (if any) to measure MV while shooting a PRS match?

    Aerodynamic Jump ?? Effect just at the muzzle or down range as well?

    AJ is neither a perturbation happening in a definite point or a perturbation ocurring over an extended space-domain, being actually a Regional transformation. This can be proved in terms of Yaw and Lift, and mathematically by the EOMs, meaning AJ is the outcome of the change in transverse CG...

    Aerodynamic Jump ?? Effect just at the muzzle or down range as well?

    You need to take a step back and check the equations (the real ones...not simplifications) of both vertical perturbations...and you will come to terms and understand why this is a WRONG answer in regards to wind-induced AJ, which is a transient effect. I would have preferred not to say anything...

    Aerodynamic Jump ?? Effect just at the muzzle or down range as well?

    To avoid a bloody mess with a long rant, I say, NO, any vertical downrange perturbation cannot be the result of wind-induced AJ, despite the fact the Lift force is always present. Now regarding downrang AJ...steady coning motion causes little or no further net angular deflection of the...

    Aerodynamic Jump ?? Effect just at the muzzle or down range as well?

    I guess it's critical to realize that not all perturbartions, even looking alike, are caused by the same base effect/reason, and some are transients and some are not. In a simplified way, Wind drift is a consequence of DRAG force, while AJ is caused by LIFT force. This Lift-effect moves the CG...

    Aerodynamic Jump ?? Effect just at the muzzle or down range as well?

    In angular terms, the AJ is constant. Obviously not in linear terms. NO wind at the muzzle...no AJ. Again no, later on the bullet will not be affected by AJ. I'm assuming you are referring to wind-induced AJ and not by Lateral Throwoff.

    ColdBore from Patagonia Ballistics, and TRASOL, which runs on Patagonia's proprietary ballistics engine. Excellent out-of-the-box ELR accuracy.

    Seeking Alpha Testers for Ballistic Calculator

    Looking forward to read your paper on the engine details. I'd say that most ELR shooters are not really "influenced" yet curious because there are so many apps all claiming being the best, that the market is over saturated to garner any interest over the already established apps, which are trued...

    Seeking Alpha Testers for Ballistic Calculator

    You mean something like Gravity Ballistics or Piton-Bressant? More details would be interesing to have in order to correctly evalute it. Can you post some sample data?

    Would be nice and help a lot if you can develop on how this new software works. And what you meant by "without special equipment"...

    G1 & G7 Tables?

    I do and unless you can show some data backing your statemente, I stand correct. Call it AB profile and that would be fine. Renaming things in a funny way, only contributes to the general mystification of this matter. You said If that makes sense. Essentially it created a G7 Rev III 2016...well...

    G1 & G7 Tables?

    Hard to say, because the original G7 is an english design not sized like the G1. So, it'was not a 1.00" 1 pound sample. Subsonic is very interesint but usually very stable, I think most interesting is the transonic region. Makes sense?

    G1 & G7 Tables?

    That's a cubic polynomial...not a cubic function. Not the same thing though. In summary, a cubic polynomial is a function represented by an expression, while a cubic equation is a statement that sets the polynomial equal to zero and asks for the values of x that satisfy the equation. On the...

    have you tried ChairGun? It's even better designed than Strelok IMHO

    Range Report WHY GRAVITY BALLISTICS?

    Would be nice if someone can make a step-by-step short video on the method and app working together. You know, an image is worth a thousand words, and a video is probably worth a million words :cool:
