NOTE: Yes/No questions are answered with the YES and NO keys. No SET is required. Also, Any
time you are messing around with the Ballistic Calculator and you realize you've painted yourself
into a corner hit (gently now) the NO button until you exit the mode. This will take you out of the
Ballistic Calculator. Then hit TRAJ again and it will let you start from the beginning with the last
things you entered as the defaults.
EXAMPLE: Make a trajectory printout
If you haven't already pressed the TRAJ do so now so that the screen shows:
ENTER VELOCITY: 2500.0
Let's change the velocity to 2650 and press SET . The Ballistic Calculator will now ask you
for the Ballistic Coefficient (BC) . This is always a decimal number but the Ballistic
Calculator is smart enough to add the decimal if you forget it. Enter a BC of .475 and
press SET .
NOTE : The Ballistic Calculator will only produce correct results with “C1” ballistic
coefficients. This is the industry standard and is what you will find in every bullet
manufactures current specifications even if they don't label it as “C1”
Enter Conditions:
Next the Ballistic Calculator asks you if you want it to use Standard (sea level, 59
degrees) or Nonstandard conditions. Tell it YES to accept the standard conditions. If you
answer NO it will ask you for altitude and temperature information. Based on the data the
Ballistic Calculator will correct the BC to your nonstandard conditions.
