When you set up the chronograph, did you have it set up exactly the same distance from the end of your barrel each time? They need to be set up a minimum distance from the muzzle, mine is 5 to 15 feet.

Did you shoot at the same time of day? Different light levels and angles affect the reading, ideal is middle of the day when the sun is at its peak.

As @Mooseman has said, next is the shoot test also called validation. Use the speeds you got and punch them into a ballistics calculator and see if it matches up. If you only have 200 yards then that'll have to do. Can you think of any public land nearby where you can shoot at a slip at a further distance? Validating the speed is key before you send away for your cds turret.

Chronographs will get you in the ballpark, testing the data is key.

Nah was different time of day also so that probably added to it all, roughly the same distance but I didn't measure it. First thing that comes to mind is Seddon rifle range, that goes out to 1000 yards but I'm not sure what the rules are in regards to shooting there or getting access, no idea about doc land. Odds are there's probably somewhere but I don't know about it haha
