I am setting up a new M3 .30 cal 700mm sniper using fx hybrid slugs. Here is the following information that I can enter into Strelok Pro

Scope ATACR 7-35 F1

Height 2.86

Zero 40yards

length .420

diameter .30

weight 44.5

ballistic coefficient .102 (listed on fx website and some other places)

speed 973 fps

I sighted in at 40 yards, then again at 100 yards. My question is Strelok is saying 33 clicks(from 40 to 100) but my scope says 38 clicks. I must change my Ballistic Coefficient to .06

to get strelok to say 38 clicks. Is this the proper way to do this? 

Also using drag function GA. I tried different ones and it stays almost the same.

Look at the lower right hand side of the main screen. There is a target with an arrow pointing up and down. Click on it then you can adjust what your rifle actually does. Set your distance, then select how many clicks you are physically using.

GA is not a suitable drag function for slugs, particularly at speeds approaching 1000 ft/sec. The BC quoted by FX may well be based on the G1 drag law again not suitable for slugs giving artificially high values at higher speeds, good for sales, not good for trajectory modelling.

RA4 is better for slugs, though it does depend on the slug design somewhat, though you will have difficulty finding BC values for slugs based on RA4. SLG0 is a slug specific drag law but probably not available on Strelok.
