I've taken both LB and Exbal out to 1450yrds quit a bit and LB is right on with the G1 BC I was using while Exbal was 2 MOA low. To get Exbal on was not hard but require multiple BC's which LB did not require nor can you use with LB. LB has the ability to use G7 or G1. LB is kinda slow to get open but once open it is fast, Exbal is fast but I've experienced a lot of it dieing and needing to reboot which makes it frustrating to use. LB has multiple wind zone capability. I don't know if you want to deal with Spin drift and Coriolis but LB does a great job with them, Exbal is workable with this variables.
Loadbase is much easier to save and retrieve different loads and targets from! Exbal has trajectory validation out to 1000yrd, which has proven to me the best feature, I've dialed in 4 rifles this past month and all have made kills with little more work than a validation but that seems to only hold a little ways past a 1000yrds for me.
LB now has a Kestrel
screen if you link to the new bluetooth capable Kestrel, and is GPS capable also for targeting, giving you range, azmuth and slope. I haven't played with the GPS targeting part but it looks like it would be amazing if set up correctly.
Loadbase is set up so you can shoot your loads and find the BC and drag specifically out of your set up then use those numbers, also has ability to compensate for powder temp. Exbal has a simple trajectory validation then you have to tweek to keep it on at farther distance.
Loadbase is a complete ballistics solution, with great after sales support and regular updates. Exbal is simple and works good for simply tweeking till right then leaving it alone. If you are kinda into techy stuff LB is the way to go, if you have a hard time with computers Exbal is the way to go!
Loadbase 3.0 comes as a bundle from Patagonia ballistics with desktop and PPC versions, only in the LRH gear shop you can get it separated for less.
By next Fall I'll be running LB on a Trimble unit with a GPS module linked to a blue tooth Kestrel getting live enviro data while it is out in front of my shooting position on a weather vane on a tripod. And Exbal will stay on my PPC for fast, close shooting. I could make a case for both really!
