hi everyone, this is mostly about how my shooter app seems to be a bit off for a while, when It used to be bang on.

i have found this with two riffles, my .223 and 7mm magnum.
I know you need to verify your drops and in the past I have, and found the shooter app was very accurate.

with my 7mm, how I zero is basicly get the windage right at 100, and as long as the elevation is about 1.4- 1.7 inches high (which is roughly the 200 yard zero I want) I just input how high exactly at 100 it is, into the shooter app. rather than trying to get say... a bang on 200 yard zero. for me this works for about a 200 yard head shot, or any further and I will be dialing for correction anyway.
and this has worked.

but lately iv found the shooter app to be out. the other day it was low at 360 and 700.at least a couple of clicks, if not 1 moa at the 700. I needed to check the zero today and it was high by .5moa at 329. it said come up 2moa, but 1.5 was right.
the thing I don't get, is this is the same rifle, mostly the same inputs (except maybe how high I am above zero at 100) and the same load.
my .223 is also high, at least a click or two from memory (at 330) and has been the last few times iv done the zero. (it gets a 100 yard bang on)

using this app has one down side... its not written down so I cant remember what iv dialled in the past, I think maybe, 1.75 moa. for 330 yards

my zero is 1.6 inch high at 110 yards (its a meters range)
162 amax 3100.

if I adjust to 1.8 high its still 1.8 moa I have to come up.(still a click out)

like I say, it was never like this it used to be accurate, has anyone else noticed this using the shooter app....
how do you zero, do you use an app...
