I’m having trouble entering ballistic data the atn lets
Me add the figures I need but once I’ve pressed
Enter it changes the figures...ie bullet weight is 8.4
Grains but changes it to 10grains😳my coefficient
Is 0.018 but it changes to 0.2 on entering.Also when entering a known range,it won’t go below 25 metres

Minimum scope and ballistic settings. Although I can set my BC to .08 for crossbow usage.
A ballistic coefficient of .018? Like throwing a brick. Pretty low b.c.
I don't profess to know the programming logic or all the minimum profile cut-offs.
I also can't get a smart shooting solution below 27 yards. 25 meters, 27 yards...couple inches difference. Minimum SSS range.
Although I hear you can obtain a shorter target distance SSS if using a blue tooth range finder for input. Don't have one yet, so can't verify that.
Blue tooth range finder is next on the list.
Choose Wisely
Shoot Straight

You are an Airgun shooter like me as you are using JSB Exacts at 8.4grn? I switched to using Bisley Magnums at 10.5grn so I could input the ballistic data and zeroed at 30 yards. It’s just that we are at the very bottom end of the scopes abilities I’m afraid |

I have similar problems with entering ballistic data, I hope that your advice will help me
