Thread: Driving your ballistic app

So how do you guys use your app? More for extended ranges. I'm using Shooter.

Its taken me ages to work a few things out as I went with help from guys on here.

I have a couply questions still.

I set my pressure to absolute so I don't have to enter altitude.
How important is humidity? Can get temp but humidity I cant get unless in cell range and that's from station where ever that is.
Do you guys set your zero atmosphere data for each load and enable that? What effect does this have and what does it use if you don't enable zero data?
At what distance do you begin to bother with Coriolis?

What other tricks or things I should know about?

Regarding humidity.. here's a nice experiment to see for yourself.

Set up your solution for a long way off, as far or further than you'll ever likely shoot on game.

1. Set humidity to 0% - Note drop.

2. Set humidity to 100% - Note difference in drop.

3. Set humidity to 50% and leave it there forever.

I just use 50-70% humidity as we don't have issues with it generally in NZ. Doesn't have much effect anyway if you're not shooting bullseyes.
Always use station pressure off my kestrel or watch as it has proved accurate in the field.
Get them and your angles right and your good to go.

Sweet as, my garmin 650 does pressure so will use that.

I leave humidity at 50%. I don't worry about coriolis, but the furthest I've shot at game is 600 yds. Past 500 yds it will start to make a difference.

I tend to find a glassing point and sit and wait. When I get there the first thing I do is set the pressure and temperature, select the rifle I am using etc. Then when I see an animal the only thing I need to do is set the range and angle.

if your phone is capable ( mine is galaxy S4) then it is able to read humidity, temperature and altitude from the sensor, so just put in that data from the phone, rather than relying on an internet weather station that's no real relevant location to where you are

set my zero atmosphere data when I zero the rifle, so say the range is 100m above sea level and humidity is 60%, temp is 17 degrees and pressure is say 1010hPa that day, then that be comes your zero data

600 plus all these things wil take effect, angle is most brutual if you don't get it right

Zero atmosphere only becomes important if your zero is a fair way out.
Zero at 100y or m atmosphere is pretty negligable.

Sweet as. Yeah i make sure my zero is spot on. My rangy does angle so no issues there.

By a fair way out I ment if your zero was at say 400y for whatever reason then a change in atmospheric could change your zero and shooter will account for that if zero atmosphere is enabled.
But if your zero is at 100y any change in pressure you are likely to experience is going to have very little real effect on your true zero as it has so little atmosphere to travel threw on its way to 100y.
So zero atmosphere not required if zeroed at close range ie 100y

Ah that makes sense. Cheers man. I will disable it so its one less thing to think about. I do zero at 100.

Your phone will have one flaw - the temperature is always reading about 26deg....about the same as a running lithium ion battery. It can be tweeked with a third party app but then the corrected temp can't be fed into 'Applied Ballistics'. I had shooter but I found AB to be easier to customise.

Could buy a suunto watch, will give you pressure and temp if you take it off your wrist

One thing I've always wondered about the app inside the kestrel - can it have the clicks true'd up like you can with AB? I have to do that because my clicks on a march are not to the same std as AB. Can the custom function just enter real world POI data?

I had the s4 samsung and it would give very close readings to my kestrel.
this is the only phoneI know of to have the 3 sensors.
my s5 samsung does have pressure but I do miss the temp.
humidity doesn't matter till ya long ways out.
I have used the balistic watch which is great if ya have the one rifle.
next purchase might be the latest kestrel that litz and hodnett have been working on.
my mate scored one and reckon they are the ducks nuts!
the 2500 kestrel does all you need until ya get past how far the 338 goes.
also fuck shooter ap as it has glitches that he won't fix.
AB is more expensive but you get all litz's real world bc data and latest projectiles updated and always improving it as well.
I like his truing function to as they are also working out the magnus effect which happens further out than I can see!
keep your app on simple and don't think about coriolis til you've mastered to 1000 and even then wind and spin drift will fuck ya up before the spin of the world will!

If you're on pressure is absolute isnt temp irrelevant?
