I have a 6.5 creedmoor shooting 140 gr Amax. I punched in the hornady match 140 amax to configure and it used the standard G1 ballistics so after some research I found that Litz's G7 should have been what I should use so I changed, but after shooting all dope that the shooter app gave me was approximately 100 yards long for example to hit from preconfigured data at 200 I was using what was called for at 100. I calibrated my actual dope at 400, 600, and 1000 and Shooter adjusted the velocity settings to accomodate this DOPE. My question is should I still be using the G7 by Litz or use the recommended settings of shooter which is G1?
When using shooter app which ballistic profile should I be using?

Gun, I am having problems with Shooter app as well. See my post from several days ago - the data that comes pre-populated in his library does not appear to match the values in his book or on the website for the actual ammo manufacturer. I have emailed the "support" email address for the app several times and so far no response at all.
Well I never thought about the possibility that the program might be messed up. I assumed I was utilizing the tool in the wrong way. I just got an ipad and I am thinking of moving to the ballistic ae advanced program. I really lile the ability to take a picture of a group then scale it, measure it, and save it. I just can't seem to get the search feature to bring up much data on ballistic apps.
I was seeing similar issues and it ended up being the G7 BC was pulling from the Litz library incorrectly on my 162 amax @ .599 and all my drops were off. I emailed Bryan and said to manually input .307 instead and I doubled checked my data and now looks nuts on. I am using Applied Ballistics and not shooter but it sounds like the same bug... As far as the Shooter support team responding, I hope they get to you soon! It's a frustrating issue to say the least but they were VERY fast to respond to my questions.

ALLWAYS use litz if its listed... if not, you can convert g1's to g7's here
convert the G7 your self
you can do it here
G7 Flash Ballistics
or
JBM - Calculations - Drag Function Conversion
also, BC database

if you true the app, and data is way off, then.....
#1 triple check all your info is right in the app, scope hight, BC, so on..
#2 CHECK YOUR SCOPE!!! ---> http://www.arcanamavens.com/LBSFiles/Shooting/Downloads/ScopeChecking/
#3 true the app, see below
You can calibrate most software and is simple enough too do.
Some of the elements in the video “Magpul” are correct for other software, like actually shooting to a range that puts the round around 1300fps. (example)
The steps are simple enough, calibrate your scope and if necessary adjust the software using the sight offset, click value, etc. This will work with most software to include the iPhone Apps.
Then, calculate actual drop. You can start at 300 yards to begin. At this range you can adjust your BC if necessary. The BC will move based on the rifle shooting it. For example BulletFlight has an option in the utilities area to adjust BC based on Drop. it will give you a new G1 or G7 which you can then input into your data section.
Lastly you can calibrate the drop out to 800 yards like the video. Checking at distance is the final step, but you should have at least choreographed your load to start with, if you haven't then some software does have functions to adjust it based on drop.
Certain software has a DK function to bend the curve, this is used in place of adjusting the BC or MV, so you can do it a number of ways with a number of different software solutions, not just the Horus. Remember he was hired by Horus in the beginning to work and sell Horus methods and products, so of course they are not going to inform you of other methods.
Calibrating the system like above I have taken software like Field Firing Solutions and Patagonia LB3 out to distances beyond 2000 yards with very successful hit rates. Inside 1500m the first round hits where more consistent than when you didn't do it, and at 1000 yards and in it was too easy with a rifle like a 338LM.
The system calibration should be:
1. Muzzle Velocity using a chronograph
2. Scope calibration to at least 48"
3. Drop to 300 yards to tune with then
4. Drop to to 800 yards to fine tune.
