I had my son shooting today at 1360 yards. We had fun. Elevation come-ups were pretty much right on. Using LoadBase that's not a big thing.
I was shooting at a Latitude of 39° and an Azimuth was 220°
I turned on "Spin Drift" and "Coriolis" and the adjustment was 0.5 MOA
more than what Exbal predicts... Had we used Exbal prediction on a deer it'd been a miss.
Exbal is really doing pretty good considering:
1) you have to use G1 for your BC which according to Bryan Litz it's got a variation of 0.137 in BC in his testings (SMK 300 gr.) and on top of that not forgetting the fact that G1 is velocity dependent.
2) Can not use G7 for BC which is not velocity dependent and the variation in BC was only 0.024. Quite a difference. Gives you an excellent reason to use a ballistic program that would allow the user to use G7 drag BC's.
3) No practical way to use Coriolis and Spin Drift.
4) your trajectory validation is only good for the distance you validate it for. It will not do no magic for you... Don't believe it? Go and shoot at different distances... You'll find out you'll be doing a lot of trajectory validations which means it will only be good for the distance validated and it's surroundings.
I'm glad you boys are still playing with it. One of these days it'll dawn on to you!
The only reason I participate in this kind of activities is because I want to help others to find the better products without the head aches. Not because I enjoy taking sides with some and destroy others, I just merely love helping those that would want to be helped.
LoadBase is a easy as you want it to be and as complicated as you want it to be.
Being a minister for over 25 years I have gotten to know a lot about people, many once their mind is made up nothing will change it. It's like a naked woman in the middle of the street, at day time, and you go out with a blanket to cover her with, and she gets upset and says to you "I'm not naked you fool, get away from me".
I was going to do it, but I don't believe it's worth it, I was going to show how much easier LoadBase from one screen you can do so much more than most others programs I know. That's simplicity!!!
Sooner or later it'll dawn on you.
