What does an ogive measure?
Ogive Graph or the cumulative frequency graphs are used to find the median of the given set of data. If both, less than and greater than, cumulative frequency curve is drawn on the same graph, we can easily find the median value.
What is ogive bullet?
Bullet Ogive – bullet ogive is defined as the “curve of a bullet’s forward section” and can be expressed as a tangent ogive or secant ogive. A bullet with a tangent ogive is one that has the cylindrical surface of the bullet tangent to the curve of the point.
What is a bullet comparator used for?
Gauge, the Bullet Comparator provides the ultimate in precision measurement. The Bullet Comparator will properly align the O.A.L. Gauge for precise measurement using a caliper. This method allows direct comparison of your loads as you set up your bullet seating die for any selected bullet free-travel (jump).
What is a comparator gauge?
A device that compares the unknown length with the standard. Such measurement is known as comparison measurement and the instrument, which provides such a comparison, is known as Comparator. Comparators are generally used for linear measurements.
Where are ogives used?

How important is OAL in reloading?
The overall length (OAL) of an ammunition cartridge is a measurement from the base of the brass shell casing to the tip of the bullet, seated into the brass casing. Cartridge overall length, or “COL”, is important to safe functioning of reloads in firearms.

How many types of ogives are there?
There are two types of ogives : Less than ogive : Plot the points with the upper limits of the class as abscissae and the corresponding less than cumulative frequencies as ordinates.
