Each target record is keyed to an individual Firearm record and specific Load record.
The target record contains information concerning the firearm and ammunition used to produce the target. Only the targets and shots associated with the selected firearm and the selected load will be visible from this module. The selected Firearm will be visible in the selection grid at the right of the form and the load number is displayed at the top, right of the Target Records page, next to the Select Load> Database Navigator bar.
After all Shot Records have been entered and evaluated, the information may be transferred to the companion, Precision Ballistics and Trajectory module, where Ballistics, and Sight Settings may be calculated and recorded.
When a new target record is opened with the New Target> button, the current date is entered and the target is sequentially numbered.
The Sight type of the Firearm is entered and the Name of the Mold or Bullet Vendor is entered along with the Bullet Index Number.
Manually edit the correct range to the target, in yards.
The distance of the Target Range, distance from the muzzle to the chronograph and local elevation in feet will be automatically entered from the values saved in the Configuration Module.
Temperature, barometric pressure, vernier points for zero range (if applicable) and additional sight setting information should be manually entered into the appropriate fields.
All values in the data sheet are calculated or copied values derived from the information entered into the Individual Shot Records page.
Clicking on the "Comment" button will open a Comment Module where notes may be stored for each individual target
The target may be deleted with the Delete> button. This will also delete all recorded Shots associated with the deleted target.
The calculated data generated by the software from the chronograph and shot coordinate consists of:
1. The average of the entered chronograph velocities.
2. Highest velocity.
3. Lowest velocity.
4. Extreme velocity spread.
5. Standard deviation of the recorded chronograph velocities.
6. Calculated actual muzzle velocity calculated from the chronograph averaged velocities, the distance to the chronograph and the ballistic coefficient recorded for the bullet in the Load Record.
7. Calculated bullet energy at the muzzle.
8. Calculated firearm recoil energy.
9. Group size in inches calculated from the shot coordinates of the target.
10. Group size in minutes of angle, determined from group size and distance to the target..
11. Vertical group center is the distance of the group center above or below the point of aim (below center is shown as a minus number).
12. Horizontal group center is the distance of the group center to the right or to the left of the point of aim (left of center is shown as a minus number).
13. Extreme spread of the Vertical shot placement.
14. Extreme spread of the horizontal shot placement.
15. Standard deviation of the vertical distance of the shots from the group center.
16. Standard deviation of the horizontal distance of the shots from the group center.
17. Standard deviation of the distance of the shots from the group center.
18. Average minute of angle of the shots from the group center.
