    On November 2008, Berger Bullets hired Bryan Litz as their ballistician. Bryan is well known in many sites for his knowledge in ballistics as well as his well founded scientific approach. All this is to quote some of the comments he has made in his website in reference to Coreolis effect and spin drift. Homepage of Bryan Litz - A Bravenet.com Hosted Site

    He also acknowledges the fact that there are not too many programs out there that will calculate for Gyroscopic Drift (Spin Drift)


    What has this to do with LoadBase 3.0? Well, a lot!



    LoadBase 3.0 is still in Beta but powerful nevertheless.

    Here is how easy it's to run the program to obtain Spin Drift. Amazes me that we would barely scratch the surface of all LoadBase 3.0 does.

    I want to clarify that I don't work for Patagonia Ballistics nor do I get commissions or anything from them. I do this because I get excited with a great product that would help us all. In other websites I have read comments like "It could very well be that LoadBase 2.0 is the best ballistic program in the market."​



    If you're a long range shooter, you owe it to your self to look more into it specially when the full LoadBase 3.0 comes out of its Beta mode. Do not be bullheaded, do yourself a favor.​

    I'm in love with Loadbase. I have it on my desk top and keep all my load data and range data are in one place were it needs to be.
    I have the field version on a dell axim and it has been awsome in the field.
    This is the only program I have used, so don't have anything to compare it to.
    My computer didn't like it at first and the tech support stayed with me till 1:00 in the morning till it worked.
    Nice to see that the program is continuing to evolve and gain more accuracy.:)

    Eagelet,

    I am trying to grasp the basics of spin drift and Coriolis effect. Spin drift, I believe, is from the precession of the projectile. RH twist = movement from center of the gun to the right (as viewed through the scope). LH twist would be the opposite. The Coriolis effect (maximum effect) when the projectile is fired North or South (0 or 180 deg.). When firing to the north, the target is moved from the earth's rotation to the east (therefore the POI is to the left). If firing to the north a person would need to add the spin drift and coreolis correction. When firing a projectile to the south, I think the target will move to the left (POI is to the right)? So, the spin drift and the coreolis effect act on the POI shooting north and south? But is the cumulative effect of spin drift and Coriolis on the POI one direction firing North and another firing South(POI left for North & POI right for firing South)? All this assuming a RH twist barrel. Any comments or suggestions will greatly help the little squirrel running in my head. Thanks.

    Chris

    Eaglet,

    Does upgrading from LoadBase 2.0 to Loadbase 3.0 (when it's available) require the purchase of a completely new license? I currently have LoadBase 2.0.

    That's unsurpassed costumer service!!! I'm glad to hear that!

    The upgrade to LoadBase 3.0 is also an effort to keep the program up to the new technology not allowing it to become old and obsolete. In fact,
    LB3M was developed under .Net CF 3.5 and SQLCE 3.5.1 which makes it incompatible with the current components versions.

    :) Just don't ask me what all that means!

    Phorwath,

    You, like me, I knew you'd be interested. Right now it's being tested and retested in its beta form. I do not know when it will come out but I hope
    pretty soon. Yes, this would be an upgrade and would require a new license.
    I believe it would be the same cost. I'm also the owner of LoadBase 2.0 like you and I don't know how much it would cost us, the previous owners, to update from LB2.0. I guess we'll know soon enough.

    GOOD NEWS!

    Once it comes out of the Beta Status, Patagonia Ballistic will FREELY make LoadBase 3.0
    available as an upgrade to all registered users.

    Those that for whatever reason don't want the upgrade, Patagonia Ballistics will still support LoadBase 2.0 while not updated.

    Only new users or those getting a new device will require to purchase a license.

    MORE!

    LB3D ---> LoadBase 3.0 for Desktop is also IN THE WORKS!

    Well thanks for keeping us informed. I expect Patagonia will notify LB2.0 license holders when the upgrade to LB3.0 is available. I hadn't heard anything before reading your thread/post.

    Chris, I think your little squirrel is running alright. Mine stopped a while ago. :)

    You're right, the effects are accumulative. Spin drift is affected by the twist of the barrel, the properties of the atmosphere but has nothing to do with the rotation of the earth. Spin Drift will always displace the bullet to the right if it's a right twist barrel, regardless of the direction you're shooting.
    On the other hand, Coriolis Effect has to do with your Latitude and the direction you're shooting. Producing two components, a horizontal component and a vertical component as shown here.

    [​IMG]

    The horizontal component has to do with your latitude and is not affected by the direction you shoot; the vertical component is affected by the direction you shoot and where you are on the earth. Vertical component is maximized at the equator and minimized to zero at the poles. There is, though, zero vertical deflection when shooting due North or due South. As you would know, you'd hit high when shooting east and low when shooting west just following the same reasoning you used.

    Man I hope we got this right!!! :D

    Good deal! I'm looking forward to it and studying up on the spin drift feature. I've already demonstrated the spin drift with my rifles at 1000 yds. I might as well factor it in with my ballistics software program. Thanks Eaglet.

    What if I have a left twist barrel in Australia shooting North to South? Would the spin drift and coriolis then be down and right?:D

    Eaglet, you are the king of gadget junkies.

    That sounds like a compliment!
