Version 6.4.6 of Oehler's "Ballistic Explorer" is due to be available this month. (I haven't heard, but I assume that NECO has a new version of "QuickLOAD" too.)

Since 1982, I've used well over a dozen commercial and freeware ballistics programs (I haven't kept a tally). My favorites are (a) Br�mel's "QuickLOAD" for interior-ballistics calculations and (b) Oehler's "Ballisic Explorer" for exterior-ballistics calculations. These two aren't the only good ones that I have, of course, but they've become the two that I use almost exclusively for interior- and exterior-ballistics calculations. (Cartridge-design is another matter.)

I especially like "Explorer's" on-screen comparisons of two or three loads. I'd probably prefer Sierra's "Infinity" for this if I could figure-out how to make it compare up to five loads on a screen.

I'm using Oehler's version 6.4.5, and I'm happy with it. I have no idea what's new in version 6.4.6, but I'll buy the up-date just to have the current version, as soon as I can locate my "safely stored somewhere" access code.

"Good enough" isn't.
