Re: exbal Qs
My version of Exbal does not use G7's, but I use JBM to convert G7 to G1's at the velocities that I'll be shooting and then enter a custom (multi BC bullet). I thought about upgrading my Exbal, but as good as JBM is, I'll probably use it to generate a bunch of spreadsheets that I'll just load into my Palm Pilot.
If some is good and more is better, then too much is just right.
My mind is a raging torrent, flooded with rivulets of thought, cascading into a waterfall of creative alternatives
