rifle ballistic iphone app

zulu_dawn

guys,

just wondering if any of you have delved into the world of iphone apps and rifle ballistics

from some initial research i have done, bulletflight v3 is getting the best reviews....

http://itunes.apple.com/us/app/bulletflight/id300903039?mt=8

any feedback?

(i have not tried myself yet, plus do not have an iphone yet!!)

I have JBM Ballistic FTE myself.
It is a fantastic app which is based on what is widely accepted as one of the most accurate ballistic calculator's. If you get the FTE version you will have use of the HUD which allows you to make live changes for LOS angle, wind speed/direction, distance and will also use your GPS location for local atmosphere and altitude settings.

worth googlin too is Kinghts armament bullet flight....

they have different priced apps depending on how hardcore you are :P

Knight's Armament BulletFlight is a military-grade ballistic computer that provides quick solutions in the field. BulletFlight does not output information in table format but rather dynamically gives you the solution you need now to make that shot. Current weather conditions including temperature, pressure, humidity, wind speed, and wind direction can be input, as well as angles to the target as measured by the built-in accelerometer. The app then provides highly detailed solutions out to 3000 meters. Your weapon profile includes your scope MOA/mRad per click, and hence when you provide a range to the target, the app will simply show how many clicks you need to change the scope by for that range and wind speed.

Up to five ballistic coefficients with corresponding velocity thresholds may be used for each profile to enhance accuracy, or use a single G1, G7, or G8 value.

Several built-in profiles for the Army's M110 semi-automatic precision rifle, the 14.5 inch SR16 rifle, The 50 BMG M107, .308 M40A3, .308 M24, and the 6.5mm KAC PDW allow you to get started quickly. You may alter these profiles, or add new ones.

This app is currently in combat use by military snipers in Iraq and Afghanistan.

For 55grain Hornady moly .223 from a 24inch barrel.
Now I will have to test the same on a 28" barrel and compare and contrast

I'm majorly pee'ed off with Vodafone/IFA Telecom as I still have not received my 15% IFA Countryside even though I registered in October

Will some of the software Guru's on boards design a similar Java program for Nokia??

The idea has a major appeal as all Nokia phones can handle Java.

Very handy to be able to get your tables in an instant in the field.
Especially for those with MOA Reticles on the scope.
I know that if I use the second crosshair on my reticle it is 7 inches @300 from a 200yard zero which is bunny tappingly good

I'm a bit suspicious of those ballistics tables on the Hornady website. Too many of the cartridges have exact same ballistics data even where they are different calibres.

Case in point is their data on the .22 swift and .22-250 (:D). Nobody else other than Hornady gives the swift and .22-250 the same ME.

Perhaps they manufacture them that way, but that would make no commercial sense. You have different calibres for a reason :rolleyes:

A longer barrel doesn't automatically give an increase in velocity you know. A longer barrel can actually reduce velocity with small calibres.
I doubt the small power charge in a .223 would benefit from anything more than 24", even with a super hot handload - the case capacity just isn't there.

Well, I am not talking about loading as it is not legal for the general public to do so yet, and as a member of the general public I adhere to all laws on my sport.
Trueflite who make the barrels say a 28" is the way to go for me with the ammo I told them I use.
So I am bowing to their experience here, I was told ~100ft/s for every inch until the max of 28" on .223
If it's lies I'm tellin, it's lies I've been told

T'is a mighty yoke.

You really need to chrono your rounds for it to be truely accurate though.

My next Purchase, a Chronograph!

This is a very good app for the iPhone and easy to set up and use. It will now take 3 different setup's for 3 different rounds or rifles.

Get it - its free and good.
