Judging from your replies, my worst fears are confirmed, they have re designed the calculator for 21st century man, leaving the 20th century computer illiterate in the dust. When I selected imperial measurement, I got metric, repeatedly. There were no drop down boxes explaining stuff like V1 and V2. I think my optics dollars will be better spent with old school equipment and the simple intuitive ballistic on line calculators. All I wanted to do was shoot different loads with the same gun and scope quickly with reasonable accuracy to 600yds which worked superbly with the "old" calculator. Didn't really want to have to take a computer tutorial to pull a trigger. It's an age thing I guess. In reality, I don't ever remember killing an animal further than 200 yards anyway. It was just kind of fun knowing you could shoot farther if the situation required. Thanks all for your input.
