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.


Get the update for your ExBall and you will have G-7's. I have never ever had a problem with Exball giving the correct dope as long as correct info is feed into it.

I'll agree that software is more accurate than our guns. But I have to point out that both coriolis and spindrift have vertical components. This, given fairly impractical ranges for most.

My Exbal is fresh of the press and I can not find a G7 capability. All I have is the PPC version, does the Desktop have it or can you tell me if I'm just missing something.

Re: Loadbase 3.0 and Exbal

Ran to the range and found out all I had to shoot was 5 shots so I made the best of it, almost. I broke a prime #1 rule the last time I was a the range and didn't return my turrets to zero before I got up so I wasted two shots. Got squared away and shot two at 590yrds that landed just down wind and an inch low with 1/2 in of vertical which I felt was good considering horrible mirage. Shot the last one at 300yrds for a close second range and was perfect so I feel I have some validation data I can play with next week after I get another 100 loaded. Then we'll take it out to 1030 and 1450 to see what we can get to happen.

Man, I need to save money and get an optic with a zero stop!!!!!

Re: Loadbase 3.0 and Exbal

Intersesting thread! I do not have the experience many of you have but this is what I have found so far.

I have Exbal, Mobal and Loadbase 3.0. Exbal is hands down easier for me to use. I like everything about it except its inability to use G7's.

I have Mobal but must admit I have only used it once. My smith in Montana is using Mobal and swears by it. He is doing some pretty amazing things at extreme distances using Mobal and customizing his G7 for the 300SMK and Berger Hybrids.

Used Loadbase for the 1st time in the field yesterday. I have been on the phone with a guy from this sight for hours going over Loadbase before hitting range.

Loadbase worked perfectly for me all morning out to 535 yards. I moved my AR500 target out to 730 yards (This is where my ATV decided to stop ). I ranged my target and input the range into LB. LB gave me a firing solution of 11.5 moa up. This is with a 300 yard zero. I knew this seemed like a bit much but I shot anyway. I was way high as I expected it to be.

I double and triple checked my data and it came out the same! Hmmm, I am sure it is something I am doing wrong but I had already used LB for my 300yd and 535yd target and they were scary accurate. At 730 yards something was amiss, probably me.

In my mind I had no choice but to try Exbal. I loaded my data in Exbal and I think it gave me a fire solution of 8.5 up. I connected 5 of 5 times at 730 yards.

I know that I had to do something wrong with LB but have not figured it out yet. I will try and figure it out today. All I know is that if I were in an actual hunting senario and would have taken a shot at a live animal at 730 yards...I would have missed completely or maybe wounded an animal.

Guess what I am saying is LB might be a little post graduate for me at this time. Exbal is so easy, even a caveman like me can use it and get the job done! I have not given up on LB. I think it is a great tool but I have my 1st hunt of the year on the 20th of this month. It has taken me 13 years to draw this tag. I will use whatever program works the best for me as I draw closer to the hunt. Right now Exbal is in the lead

Good for you. Thanks for putting the time and effort in and sharing the findings.

When you factor in the error factor of the combine package of the rifle, shooter and ammo along with the wind, many seasoned LR shooters believe it becomes irrelevant, or is smaller than the capability of the rifle, shooter and ammo.

I think it depends on how windy it is where you shoot and hunt. Spin drift plus Coriolis drift combined are very evident for me.

The part of this argument that gets hard to follow is the dismissal of ~8-11 inches of rightward drift each and every shot at ~1000 yds. I have to believe it's being accounted for one way or another. But obviously not with predicted dope if the ballistic software doesn't provide the option.

This rightward drift is occurring whether it's windy or calm. Even 4" is relevant for my shooting. Let alone ~8-11". I can understand how it might be difficult to separate the drift from wind drift if it's always windy where you're shooting. I don't see how it could be considered irrelevant. I suspect it's being built in to the doping one way or another. As long as it's allowed for, the end result is the same.
