Re: Just got a I-Phone- best....?
I use Bullet Flight and like it a lot. I have my .243 in there with 3 different bullets, my .223 with two bullets, my .22-250 with 3 bullets, my .30-06 with 2 bullets, and my 7mmMAG with two bullets. All I have to do is pick the rifle and load I'm using, enter the temperature, and wind, and I'm good to go in seconds. I have it calculate a drop table, stick it in my shirt pocket, and I have a ready reference to look up what I need to make a shot.
The multiple rifles with multiple loads database is a wonderful feature.
