    I've been scouring this sight and others for a good PC based ballistic program. I have infinity but it has drawbacks. I only need exterior and need to be able to input G1 or G7, twist data,etc. for spindrift, and the other basics - temp, alt. etc. I was going to order Patagonia but frankly, both Lens description and the website sounded a bit complicated. Can a contractor of average intelligence figure it out or are there simpler ones?

    I have Sierria's Infinity too and not what I expected . It seems to be well received by most ? :rolleyes:

    LB 3.0 is Extremely easy to use. That's if you stick to the task at hand, finding drops for your shooting distances.

    As your knowledge increases, LB 3.0 has what you need to allow you to grow without having to buy another application.

    It's extremely accurate not only for calculating for supersonic velocities but also shines when your bullet goes subsonic.

    You'll have a very hard time finding a better application that will do so much for you. You can only do as much as you want.

    Let's say you just want to go shoot your rifle with the data you have and you just want to calculate a very simply but accurate drop table...

    When you open LB 3.0 (PC version), it presents you with the following:

    [​IMG]

    That's 5 different powerful modules that will only be used at the right time.

    Right now we only care for the Ballistic Module, so we just click on it...

    LB 3.0 Presents you with:

    [​IMG]

    If you enter values in the red-lined boxes (to make it simple), you'd be entering info that you would have to enter in any other application you get.

    If you don't know all the environmental conditions, just leave the default values and enter the elevation of where you'll be shooting and LB will calculate the std values for that given altitude which for most practical purposes will be enough accurate. If you need on the dot values then enter all the right environmental conditions.

    Once done just click on the tab "Results-1" and LB 3.0 Will present you with a drop chart all the way to 3000 yards in the increment that you select.

    I Changed the linear option for the MOA in the red-line box.

    That's it!!! You only used what was needed and it just can't get easier than that!!!

    If you wanted to save it, you just fill the three empty lines and depress save.

    The values in RED at 2100 yards are indicating the the bullet's velocity is subsonic.

    I hope that helps!!!

    Now THAT'S a program I can understand, thank you very much. I was just playing with a trial download of Ballistic Explorer and, in the opinion of this compuer unfriendly shooter, it sucks. After 1/2 hour I was still unable to change my 0 range, the B.C. kept going back to .500 by itself, and although I could pull up a graph to 1000yds, the charts only went to 300.

    Another good thing about LoadBase is that if you have a scope that doesn't track exactly like the turrets say they should you can output the data in actual turret movement.
    My Sightron S3 moves about .28 per click as an example and when you start talking 20 moa+ (80 clicks+) that adds up to a fairly large error.

    I never claimed to be smart, but after reading the whole spiel about drag coeficient on Loadbases website, I'm still not understanding how to arrive at the value to enter it.

    Bedrok,

    LoadBase is a great program and not that difficult to use, it should work well for you. Another option is to get a copy of Bryan Litz book, Applied Ballistics for Long Range Shooting. It comes with a CD of a program developed by Bryan Litz. It is simple and easy to use and should give you everything you need + you get the book which is a very useful reference.

    Think of the DC as the fine tuning function, if you have a rock solid BC like one from Litz you will likely leave it at .500 but if you need tweak the trajectory a little you can add or subtract a little by adjusting from .500.

    As Eaglet has said though if you have to tweak DC more than 10% then you have BC issues and those need refined before fine tuning with DC.

    The function of Loadbase is fairly easy and intuitive to me, getting it down loaded and the license loaded seems to be the most frustrating part for most, the Loadbase tech support is second to none!!

    +1 on bigngreen post! 10% on either direction or just ±10%

    Now if you're one of them folks that want to take advantage of your LB 3.0 and your chronograph(s) and wants to get into finer realms then start LB 3.0 application, click on the analyzer module and then on the "Drag Coefficient" tab fill in the info and you'll get something similar to this:

    [​IMG]

    It's really awesome! As you can see, you need 4 distances, 4 velocities, environmental conditions and LB 3.0 will calculate for you amongst a bunch of goodies G1, G7, DC etc.

    I just love knowing is there for me for when ever I need it!!!

    Thanks to all. Loadbase it is.
