[QUOTE="ss7mm, post: 305597, member: 5"] Guys: I contacted Gus this morning and in a couple of emails he has supplied some very interesting news. He said it was o.k. to share the correspondence so here goes. I sent him an email and asked him about any future plans for LB to utilize the G7 drag form and I told him that most serious long range shooters considered it the way to go. Here is his reply................. ========================================================== Hi Dick, Let me start by saying that LB3D is almost ready to roll. Just need to finish some new features, since it's not a revamped LB2, it's a complete rework, making it a 100% .Net-based app (same as LB3M), which entitled a LOT of programming work, including some new features. I've been busy developing and delivering the new ballistics system to be fielded by the British Army Sniper Teams, and that took some time off LB3D. On the other hand, LB3M next update is almost ready too, which incorporates some changes to make it fully compatible (features and functions) with LB3D. A new and novel method to account for MV/Air Temp compensation has been developed (to fit the British requirement...lots of math there!) and will make its way into LB3D/M. Both, will do exactly what you've asked for. To give the user the option to choose between G1/G7, among other things. So, as you pointed out, no further need to use the Analyzer. In fact, I've been discussing that with Bryan some time ago (he already posted that LB is one of a few to handle G7), then I decided to make life easier for those believers in G7... Just let me point out, that LB3 ballistics engine does not rely on any "G" function at all, however to make things simpler it uses a known BC (G1 or G7 now) as a "starting point". I prefer not to go into the debate of G1 vs G7. But just let me say that G7 is neither new nor the Holy Grail. It's just a good form-factor to same bullets, while bad to others. Hope this make the wait worth! Gus ================================================================ I then replied that I knew the G7 was not the end all of ballistic problems but I felt that it would be a more accurate place to start than with G1. Here is his reply............... =============================================================== [COLOR=black][FONT="]Dick,[/FONT][/COLOR] [COLOR=black][FONT="]Well, improving the software is always a high priority, especially to listen to user’s feedback, it’s important to make the end user into the development cycle.

We'll see how thing go but it sounds like Gus is continuing to do what he always has and that is to improve LoadBase and try to give us the best software out there. [/FONT][/COLOR] [/QUOTE]
