Thread: Chronograph thoughts

Chronis can be finicky, they need direct sunlight for bewt results. That is sunlight shining straight down on the top of them. The sun shades seem to make a difference on mine (Prochrono Digital) as in it works better with them on regardless of the weather.

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.
