ericF said: I think you will find that Applied Ballistics is probably the most well regarded. My personal opinion is that Strelok would be next over the apps you mentioned. Be careful comparing two dissimilar things that appear to be similar. For example I was messing with my Kestrel elite and comparing some data to Strelok+ at 100 yards.. Brayfield funeral home
