Joined a new range and it has 100, 200, 300, 400, 500 and 600 yard berms.  Can anyone give me a rough bullet drop chart for those distances in MOA?  I don't have a crono or a ballistic calculator.  Farthest I have shoot is 200 yards.

1001' elevation
Larue 16" 5.56 Stealth barrel with 1:8 twist
Norma .223 77gr Sierra MK HPBT
BC .372

I'm shooting this ammo

Well since its .223 the velocity that is on the box is probably tested out of a 24 inch barrel its gonna be moving pretty slow. 75 grain .223 moves at around 2400 for me out of a 16 inch barrel so id guess around there. But I could be wrong.

I was able to hit an 8" at 300 with a 4 MOA holdover after confirming my zero at 100 yards. I really didn't have much time today.  Going to try and make it out there tomorrow if I can.

I was shooting some Georgia arms 75 gr 223 yesterday. I got average of 2640 fps with 16" barrel
My brother shooting IMI 77 gr 5.56 razor core through a 14.5" Noveske getting average of 2650 fps.
You should be some where close to this I would believe.

100 yard zero ( scope with 1/4" a 100 adustment)
200 yards.  8.7 clicks or 4.6"
300.       -     21 clicks or 16.5"
400.       -     36 clicks or  36"
500.        -    53.5 clicks or 53.5"

That should give you a good starting point.

I was right at 50 clicks at 465 yards yesterday.
