Bc Calibration Data Sheet

[zini 1,939]

Here lads,

 

For the ones who are interested in calibration and Chair Gun Pro, here is a template that i have produced to assist in gathering your own information when working out the BC of your pellet.

 

Its simple to use.

 

1. Zero at your preferred zero range as normal making sure that you get 3 pellets on top of each other.

 

2. Move this sheet to either 40, 45 or 50 yards and place it with a safe back stop.

 

3. Putting the cross hair on the center of the red circle, fire 5 shots as steady as you can.

 

4. Once you have the 5 shots on the sheet find the average point of the group and record on the data sheet how many cm the pellet as fallen from your zero range to the range of the sheet.

 

5. Go onto Chair Gun Pro and with all your correct data filled in, right click on BC and press BC from POI change.

 

6. Fill in the spaces with your data and press enter. CGP will then give you the correct BC.
