    Rifle Scopes Metric mil reticle subtension...coincidence?

    Re: Metric mil reticle subtension...coincidence? By definition the miliradian subtends an arc that is 1/1000 the lenght of the radius. So at 100 m one mil subtends 100/1000 = 0.1 m = 10 cm And 100 yds = 300 feet = 3600 inches, so at 100 yds ome mil subtends 3600/1000 = 3.6 inches

    Rifle Scopes Opinions on 12x vs 16x?

    Re: Opinions on 12x vs 16x? If you are planning on shooting mostly paper or small targets, or hunt at 250+ m the 16X will be the best choice. I don't have problems with mirage around here, with our horrid hot temperatures. If you must have the FOV to quickly locate something closer, or...

    Range Report All of our Ballistics Programs are now outdated?

    Re: All of our Ballistics Programs are now outdated? From a practical standpoint, nothing will change. As JBM said, drag is not an analytical function, and that's the main issue. But my hat is off to this young genius! "Nerd" to be sure, but it is people like him who little by little (and...

    5000 meters+ Supersonic (*Updated with pics*)

    Re: 5000 meters+ Supersonic Noel, why don't you just sue him if you want? And THEN come here to tell us about the ruling? All this endless whining in a public forum (where nobody knows the history, or cares about it) is just an epic soap opera that reflects poorly on you.

    Advanced Marksmanship Wind read- More important at gun or target?

    Re: Wind read- More important at gun or target? If you want to do a VALID comparison, you have to put some wind meters across the trajectory, at the correct height. Then, with real time readings choose which reading(s) you use for that shot. Asking several people what the wind is doing...

    Advanced Marksmanship Wind read- More important at gun or target?

    Re: Wind read- More important at gun or target? And of course max ordinate (and wind velocity) at "mid range" shooting at 500 yds with a 308 is very different than shooting at 1000 yds.

    Advanced Marksmanship Wind read- More important at gun or target?

    Re: Wind read- More important at gun or target? It is very easy to calculate the wind influence in each segment with any ballistic program: 1- calculate your normal trajectory (say, up to 1000 yds) in 100 yds increments. 2- now you have velocity and wind deflection at each 100 yds interval...

    Ballistic coefficient G1 and G7

    Re: Ballistic coefficient G1 and G7 I've just corresponded with Geoffrey Kolbe, of Border Barrels. He uses a version of McCoy's "McDrag" program in his bullet drag simulator, and states: <span style="font-weight: bold">"A number of the drag factors depend on the Reynolds number, which will...

    Rifle angle shooting

    Re: Rifle angle shooting For a 1000 yds shot you have less than 40 MOA from your 100 yds zero, and this is only 2/3 of a degree. Don't worry about it. Check this http://www.exteriorballistics.com/ebexplained/article1.html

    Ballistic coefficient G1 and G7

    Re: Ballistic coefficient G1 and G7 Bryan, I know you did not made this up, and know how to theoretically calculate BCs for each caliber, etc. Just don't buy it, for <span style="font-weight: bold">accurate</span> calculations what about the airflow dynamics? Are they the same for a .17" or...

    Ballistic coefficient G1 and G7

    Re: Ballistic coefficient G1 and G7 Bryan: "Clearly the drag curve, being non-dimensional, is not affected by the caliber or mass of the standard projectiles, but only by it's shape." So, are you saying that you can take a .17" caliber bullet and a 1.0" one, both with the same shape and...

    Ballistic coefficient G1 and G7

    Re: Ballistic coefficient G1 and G7 "Actually, the diameter and mass are irrelevant to the drag curve. It doesn't matter if the standard projectile is 1", .30 cal, 20mm, etc. Mass and cross section are accounted for separate from the non-dimensional drag curve." I disagree... while sectional...
