[QUOTE="JRu, post: 329563, member: 6837"] Our cell phone software is feature complete and bugs have been ironed out as far as I can see. I had to remove localization support for the time being ( to hurry up some heavy code refactoring ) so just metric for now but it'll be quick to re-implement imperial units, it seems we're in no big hurry as far as distribution channels go... Still looking for interested parties to take care of distribution or to buy the whole IPR off us. Toyed one day with G7, below is a mrad elevation comparison chart of our "G7" vs. JBM. 190SMK @ 900 m/s, std ICAO conditions, 5 cm sight height, 100m zero. G7 BC 0.270. The bullet goes subsonic already at 1200 meters so a mere 0,1 mrad of error at 1400m isn't too bad at all! Of course the error would be even further out if the bullet started off with more velocity, this is something like a 300WM load ( I get 850 m/s in my 23" 30-06 with N550 ) . [code] range JRu JBM 200 0,4 0,4 300 1,1 1,1 400 1,9 1,9 500 2,8 2,8 600 3,9 3,9 700 5,0 5,0 800 6,3 6,3 900 7,8 7,8 1000 9,4 9,4 1100 11,4 11,3 1200 13,6 13,6 1300 16,1 16,1 1400 19,1 19 1500 22,6 22,2 [/code] I'm not sure of how correct JBM is but as far as I know it's close, and this is just to point out we can fit different types of curves without any changes to our software -- G7 as an example. I still think it's pretty awesome for something that goes with you all times ( normal cell phone ) . BTW -- Thanks a lot Bryan, now we need to make another name change for our software! ;) [/QUOTE]
