I have been running ballistic programs back when DOS was the operating system. There's been more ballistic programs that I care to remember and talk about including those that you run online, those that you download for free and those that you pay for. The most satisfying ones to my personal likings and needs are:
For my PC: Ballistic Explorer and LoadBase 2.0
For my PDA: Exbal and LoadBase 2.0
Though LoadBase 2.0 is really all I would need and more, I do like some features of the other ones.
If I'm playing around and want to shoot rocks over 2000 yards, Exbal in my PDA will not go passed 2000 yards; LoadBase will give you a trip to 3000 yards, not only that, you're hard pressed to find a more accurate ballistic program for extreme ranges up to 3000 yards. Of the long list of things that my PDA version of LoadBase 2.0 will do, here are some of the ones that that come to mind:
1: Multiple Wind Zones.
It will calculate up to three different zones for the wind; let's say from 0 to 700 yards the wind is coming from 90 degrees at 5 mph but from 700 to 1200 is moving at a different speed from a different angle; you just enter that info for the zones and you're done!
you can either enter on location pressure without the need for elevation or sea level barometric pressure and elevation. On the same screen will display the sight-in conditions and the new location conditions. Cool!
3. Shoot Screen.
This is where you enter the shooting range and obtain the come-ups for your turret as well as windage. On the same screen it gives you the option if you want "Clicks" or "IPHY" or "MOA" or "MRAD", if you want the coriolis efect figured into it. Also on the same screen... no... is not horrible and bussy, on the same screen gives you the option for "Zero Stop".
4. Zero Stop.
As explained above, it is on the same screen of where you get you come-ups for elevation and windage.
If you have 3 targets at different distances, like one at 500 yards another at 575 yards and the last one at 625 yards. You enter the range of 500 and it might say: UP 7.2 moa; Right 2.4 moa. After the shot you want to enter the next target but before that you click on "zero Stop" and when you do that you see it says "zero stop set at 500 yards" and the Elevation and Windage info is set to zero. Now to enter 575 and it will display: UP 2.0 moa; right 0.4 moa; now you shoot and get ready for the next target. Uncheck and check the zero stop, now your zero stop is 575 yards, elevation and windage are set to zero,enter the next distance which is 625 yards, it will display: UP 1.4 MOA; RIGHT 0.3 MOA... It really is very easy and just awesome!... I hope I explained my self...
Well this has been a lot of typing already and I have not even scratched the surface of what LoadBase 2.0 from Patagonia Ballistics can do... Thanks for reading.
