Ballistic App screwy?

[johnnyk]

Running my .308, 26" barrel, 178gn ELD-X at 2720fps. BC is .552, altitude is 69ft, temp is 72.6*, BP is 30.23 inHg, Zero distance is 300yds, scope height is 1.97, scope is MOA (Leupold LRT 6.5-20X50).

I'm using the free version of Strelok and I'm getting 27.71 MOA at 1000yds. My buddy is running 168gn and his DOPE is 40MOA. Not sure of his load velocity but he shoots mostly SMK's and it may even be military ammo. Even with 168gn A-Max's he only gaining about 3moa (37) from the SMK load.

Do I have something inputted wrong or what? Can someone input my data in their Ballistic App and see what you get? I would appreciate it. JohnnyK.

I get 28MOA drop also at 1000 yards. I think your friends zero is most likely at 100 yards and yours is 300 yards . Your drop starts at 300 so it's much less than his and his bullet is lighter and a different BC .
If you moved your zero back to 100 then the drop at 1000 would be 32 MOA closer to 40 MOA . You have to make sure the inputs are exactly the same in every way otherwise they will not compare .
In JBM I get 30 MOA drop at 1000 . I think you would be better of using the G7 drag function BC for that bullet if your program can take it .
.268 G7 .
