Simple to Use
1. Sight-in exactly at 50, 75,100, or 200 yards depending
on your cartridge and bullet selection.
2. Set your scope to the highest magnification.
3. Determine the bullet path of your cartridge at the
climactic conditions you will be shooting. We highly
recommend actual firing at each distance increment
for best accuracy. Record the results of your rifle/
cartridge combination for future reference.
4. Determine the distance to your target and select the
corresponding ballistic line. Slight holdover or under
may be necessary to handle in-between yardages.
Practice Makes Perfect
The Ballistic Plex is much more accurate than guessing
holdover and faster and more reassuring to most
shooters than using target-type adjustments. The
nature of ballistics is such that everything is theoretical
and if any one of the variables change (altitude,
temperature, barometric pressure, humidity, bullet
design, barrel length, chamber fit, seating depth, etc.)
so does the ballistic performance. For maximum
accuracy, practice at long ranges under similar condi-
tions to those which you will experience in the field.
