The Applied Ballistics App doesn't have the .284 175g ELD-X to compare to the Sig numbers but the Sig numbers (G1 and G7) are different than what Hornady's Doppler Radar published numbers are. The Sigs numbers show higher BCs than Hornady publishes.
I too am having trouble with the 2400 calibrating to my known gun ballistics. I went out and used the rangefinder at 55 degrees and it worked great. I go out at 82 degrees and the range finder shows a 3.0 MOA increase in the solution at 600 yards. The known MOA was 2.75 MOA less and that is only at 600 yards. My pressure and density altitude aren't even close to what the HUD shows. My known pressure was 29.85 and the HUD showed 23.50 and my known altitude is 6666 ft and the HUD showed 9130 ft. I have tried to call Sig and can't get tech guys to call me back. They just want to talk wind and gun speed and that is what is changing the solution. I didn't put any wind in this weekend and the rangefinder isn't even close to my known data. Any ideas how to get this rangefinder to read the right pressure and altitude? Maybe a bad batch of sensors? My buddy bought his at the exact same place and time and he is having the exact same problems!

After weeks, I have found out what the problem I was having getting the Sig Kilo to match my known trajectory....I had zeroed my rifle, but wanted to have my inputs as accurate as possible, kind of just for interest, but it turned out to be a real bugger and learning experience. So I went to the target and measured just exactly how far above the center... I was 3/8" high from center. So I input that into the Applied Ballistics app on my phone which I have already validated the rifle on.
Well when I was trying to get the Kilo 2400 to match what my phone app reads I entered .338" as the zero height just like I did in my Applied Ballistics app. Had all environmental data from the kilo input on to my phone app, but couldn't get the trajectory to match..it was as much as 3/4moa at different ranges.. frustrating to say the least. Well long story short after weeks with the Sig guys and them giving it their due diligence. If you are going to enter a zero height it must be entered as -.338, lol yep it's gotta be entered as a negative. Once I fixed it the two apps we're so close it's not even funny.
I couldn't be happier with the help and troubleshooting/digging that Craig from Sig Sauer did! Really makes me feel easier about the decision to swap out the G7 for the Kilo 2400. Counting down the days until I will be heading west to get the Kilo earning it's kibbles!!
I can't remember, my spare phone used for the Kilo is not with me now. Sorry for the difference between 3/8 and .338. I just wanted to let you guys know to put in a negative if you're using a zero height hitting above the bullseye.Reynolds, did you enter -.338 or -.375?(3/8)?
