Anyone try this free app yet? I ran it yesterday and it seems to be really good.
I'm not usually one to use much of anything on the cell phone, but this app beats a paper dope sheet because it does your shooting angle, azmuth/direction, and lets you quick set your wind speed and value.
I've only loaded one gun/load so far, but I'm pretty happy with it.
I'm planning to use it as soon as I can get out to the long range. Shooting buddies have told me its good.

I'm truly a pencil and paper luddite, but this thing isn't too challenging to run at all once you load your basics.Quote:

That is freakishly close to the load I'm using in the App. 88 gr ELDM going 2745 fps.Quote:

You can type the range in.Touch the highlighted number on the scale (red in my app) and a popup opens to manually enter it.Quote:

I've listened to a couple of the Hornady podcasts discussing the 4DOF app. They claim the big advantage of 4DOF is using projectiles in their bullet library to make much more sophisticated calculations than the simpler BC/muzzle velocity calculators. They also strongly encourage using the "zero angle" feature instead of "zero range" to make it less sensitive to weather conditions (if I remember right). It was interesting. I've been using it a bit. I still need to play with the zero angle idea. But it seems pretty accurate so far.
Thanks for the tip! I'm loading the 88s to 2.50" with 23.8 gr of Varget and Wolf SRM primers.Quote:
