Ballistic Coefficient: This is the efficiency of the bullet as it travels
through space. This information is available for popular match type
bullets from quality bullet manufacturers. It is typically expressed
like .533. Some manufacturers provide this figure for different bullet
velocities. Select the one that most closely matches your rifle
load’s muzzle velocity. Many bullet manufacturers post the Ballistic
Coefficient for each bullet on their web site making the internet a
great resource for this data.
Muzzle Velocity:
This is the speed at which the bullet leaves the
barrel of your rifle. This number is the average of a series of bullets
fired through a chronograph. Typically a group of 10 shots provides a
good average. That number is expressed in FPS, or Feet Per Second.
For example a long-range target load can have a muzzle velocity of
approximately 3000 FPS. Reloading manuals are a great resource for
learning more about bullet and cartridge characteristics.
Zero Range: This is the range at which you have zeroed your rifle.
This range is typically 100 or 200 yards.
Display: You have the option of displaying your bullet’s point of
impact in Mildots, SMOA or TMOA. We recommend that you begin
with SMOA. Once you understand the concept and application you
will be better informed to select between Mildot, SMOA and TMOA.
