Ammunition Chart
 
This is an ammunition chart for simple reference and can be used for informational purposes.  The ammunition comparison chart shows a sampling of different ammunition specs for easy comparison. The comparison chart will show the date of origin, bullet diameter, base diameter, case length, overall length and velocity of each ammunition type.  The ammunition velocity is shown in fps or feet per second.  The ammo velocity is shown as a range since most ammunition types come in different strength variations based on weight and powder.
