Range Report Shooter App: What am I doing wrong?

[EFR]

After hearing all of the good about Shooter (the app), I purchased it for a Droid X for an upcoming antelope hunt.
Last night I gave it a try at 330yds. I walked up to a fantastic (for me) 1", 3 shot group, but 6" above point of aim. Shooter called for 11 clicks up. My second group, from 330yds, I dialed 6 clicks up, and hit point of aim. Shooter is about 50% off. What am I doing wrong.

I am shooting a T/C Icon in 243 Win. 42gr H4350, 95gr Nosler/combined technologies 95gr ballistic tip, velocity 3015fps avg at about 800' elevation.

The scope is a brand new Zeiss Conquest 4.5-14x50 with target turrets in Leupold PRW rings.

I can't find anything I entered wrong in the program, 1/4" clicks, bullet was in the library, my velocity came from a shooting chrony, sight height above bore was done with caliper (1.8"),the distance came from a Leupold range finder (dead on at the 100 and 200 yd known distances).

With so many satisfied users, I must be doing something wrong, but I can't figure out what. The rifle is sighted dead on at 200 yds. Shooter says I should be 1.4" high at 100, which I am.

Any help is appreciated.

The question is, what could I be missing or entering wrong?

Re: Shooter App: What am I doing wrong?

Are you using the GPS function to populate your temp, elevation, and barometric pressure? Doing this can cause problems when your station metrics don't match the info gathered from the nearest airport or weather station. If you have a Kestral 4000 or 4500 reset your shooter program to use density altitude and forget the rest.

LR-WSM: I am using the GPS for that info. I do not have a Kestrel. Do you think I would be better off getting that info from a weather station? Elevation from a map?
Thanks

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: DFOOSKING</div><div class="ubbcode-body">You did gather the right dope in the end...and of course jotted it down for future reference. I recommend shooting at a few more ranges and gather some more data just to be safe.

I wouldn't rely on my phone while hunting. I've also noticed that places where I hunt the satellite reception is poor. Combine that with no kestral and you may as well rely solely on your data. No satellite connection at all it just runs "the averages" for conditions, I'd rely more on what I wrote and know compared to an average result on a game animal. I'm sure he'd appreciate it too.

My 2 cents </div></div>

I agree. I have and use shooter. Works very well. But that is with a kestrel 4500 AND a logbook.
If it matters.... the pressure altitude, temperature, humidity, etc can be off by 20% or more at a station measuring location found by shooter versus your shooting location. Obviously, data at the location of the shot is the most important for calculation. i.e-a kestrel of any model that will give you density altitude will be a great compliment to your software

Check out these links Operation manual, Shooter and Adaptive Consulting and Training, ACT uses simple ballistic solutions based off of your bullet and known speed. You plug in altitude and temperature and the card gives you come-up's in MILs or MOA. Frank has a very good video out explaining and demonstrating the use of these cards.

Re: Shooter App: What am I doing wrong?

Fixed it. I went back in to re populate barometric pressure, correct altitude, temp etc. I found an input for bullet length, entered that, and in doing so, found what I believe was a factory preset of 100 yd zero and 1.5" sight height. Entered correct info prior on different page. New info, 2 for 3 in 4" diamond at 386 yards. Thanks to those that offered helpful suggestions.
