Phone Apps for shooting?
« on: October 01, 2013, 11:22:08 PM »
I was just watching an episode on "Modern Sniper" and they were talking about using ballistic calculators on a blackberry to come up with firing solutions for long distance shots.  Did a quick search of the google store on my smartphone, and low and behold I found an app that does ballistic calculations. Not really sure how to use it just yet, but I plan on doing some research and figuring it out. This got me thinking: Are there other good phone apps are there out there for shooters like us?  Anything you've tried or would recommend?

I have used Shooter and iStrelok. Shooter has always been spot on for me especially with the G7 numbers. Shooter usually gives you about the same numbers as JBM. iStrelok is cool because it shows holdovers for your reticle but I figure if your gonna use a phone app you might as well dial it in. I am interested in the Applied Ballistics app but its only on android for now.

Just be aware that these apps are useless unless you chronograph your loads. The muzzle velocity on the box of ammo you buy is not accurate. Every lode I measured have been at least 50 to 200FPS slower than what is listed.

+1

fps of load
bc of bullet
atmosphere
distance/angle to target
wind speed and direction

The app is just the calculator, if your input numbers are not correct you won't get the right solution.

Unless you use factory ammo with known muzzle velocity such as the .308 Federal Gold Medal Match ammunition which is running about 2600 fps...Find a military load that matches the FGMM then you are in the ball park...like 42 -42.5 grains IMR 4895 with 168 grain Sierra match boat tail on military LC match brass, or 43-43.5 IMR 4895 pn commercial brass....these are on rem700 with 24 & 26" barrels..

Factory known velocity is only good if you are using the same firearm and same conditions that the factory used to get their number - FPS is only part of the puzzle also your FPS will be different with your 24 & 26" barrels using the same load.

Yes, but if one who does not reload or does not have a chronograph then factory known velocity helps for just a baseline approximate...ball park...then one can test the ammo on their particular gun and distance

Fast is fine , accuracy is final
