SHOOTER is a really good program - very accurate. The great thing about it is that it accounts for more variables than Exbal. However, the bad thing about it is,... it accounts for more variables than Exbal,...
I love it because it's on my phone, which I always have with me. I'm able to utilize the built in GPS and weather info for my locale easily,... It has an extensive database of bullets with G1 & G7 Ballistic Coefficients as given by the manufacturer AND those measured by Bryan (Litz) - Thanks Bryan! It also can output a quick drop chart that's consistent with your variables, as well as a tailored (specific) distance that allows you to +/- yardage easily and get MOA, MIL-RAD, IPHY,..etc. It's slick!
While I love the fact that I can really get fiddley with all the inputs, I also hate the fact that I have to get fiddley with all the inputs to render a solution. At the start of the day, I'd like to just input a 'default' for my rifle i.e. bullet, velocity, reticule, etc. and be able to just hit the solve button and let it figure out my GPS location / current weather conditions, etc. and spit out a quick drop chart out to 2000-yards,... POW that would be slick! Also, in addition to the above, I think a reticule assignment of some type would be great,... this is what I miss about Exbal; I could input all my variables, get my solution, and it would generate a quick hold-over yardage/cross-hair solution for all my different scope reticules: Mildots, TMR, MOA, etc. This was really handy and really quick,... it should be a quick-menu item that would superimpose on your dropchart i.e. once you have the solution (drop-chart) be able to hit the "Menu" button, then a "Hold Over" button and it would show a quick summary of your holdovers based on the reticule you've assigned for that rifle,...
In any case, it's WELL worth the $10.00 and just plain fun to play with. I've often used it to analyze ballistics while reading through magazine articles and reloading manuals. It's interesting to see what bullet, pushed 'X'-fps will do down-range, and this program does it well.
