    Range Report Windage Effects (Ballistic Calculations)

    Re: Windage Effects @Bronco and Mouse - I tried to warn you about Carlucci. Ha! You guys are right, exepensive and hard to read book. Marginal additional info after McCoy. But, still, if you are rounding out the ballstics "library", there are less informative books out there. @TOB -...

    Range Report Windage Effects (Ballistic Calculations)

    Re: Windage Effects Mouse, I hear what your are saying about BC, but I also hate the concept. Mostly because it's a dated effort to reduce calculation labor before the days of PC's, etc. It's one redeeming feature, the ability for comaparison of projectiles has been badly abused and...

    Range Report Windage Effects (Ballistic Calculations)

    Re: Windage Effects Ahh... I should have warned you to stop at Chapter 8. LOL! Also, regarding those equations, there is a great errata document online for Bob's book. He passed on before he could fully edit his book, but several of his colleagues did it for him. Google it and if you...

    question on chronographing...

    Re: question on chronographing... A warm barrel will def. change your ES. When really hot out, I have had to space shots as much as 5 minutes or more. Also, avoid letting them "cook" in the chamber if you can.

    Range Report Windage Effects (Ballistic Calculations)

    Re: Windage Effects 1) Mathematically, it is more intuitive to set-up up NI on a time step, I agree. This will certainly solve your equations just as well. When you complete your trajectory solutions table, though, just know that you will often have to interpolate between ranges for the...

    Range Report Windage Effects (Ballistic Calculations)

    Re: Windage Effects Bronco, So, you are well on your way. My bad, I should have known from your questions that you were up to something. I would recommend you do your solution on x, not t. It will be easier to set up your trajectory tables and to do angled fire solutions. While we're...

    Range Report Windage Effects (Ballistic Calculations)

    Re: Windage Effects Bronco, where you are going wrong is assuming that the windage effects are independent of the foward motion. In fact, x, y and z travel are dependent of each other. Please refer to McCoy's chapter on 3DOF point mass where he presents the eauations of motion both with...

    Re: Internal Ballistics book Simply put, there are only a handful of PhD types on the planet that can can discuss explosion and combustion theory in-depth enough to be able to model/teach it. Back in the day when I was working on .gov projects, it took us 18 months to find and hire a...

    Rifle Scopes Luck with scope tracking

    To-date, I have always had very good luck with my Razors and NXS's with value/click to be very close as advertised. Some of my cheaper scopes, not so much. All of this is somewhat expected, of course. So, my question is this. Have you pretty much had the same experience with your higher-end...
