[QUOTE="FEENIX, post: 1914567, member: 14204"] According to Ramirez and Ramirez (2003), [B][I]the present invention provides a method of determining the efficiency of a gun cartridge by determining the water weight volume of the cartridge; determining the bore diameter of the gun barrel; determining the weight of the bullet, and calculating the efficiency rating of the cartridge by multiplying the water weight volume by the bore diameter and dividing by the bullet weight. The efficiency rating is optimal between 110 and 145[/I][/B] when the water weight volume is determined in grains, the bore diameter is determined in thousandths of inches and the bullet weight is determined in grains. In their gun cartridge research study, the inventors from HALO50, Inc, offered the following definitions: [B][I]Efficient:[/I][/B] Marked by an ability to use the most effective and least wasteful means of accomplishing a purpose or doing a task. [B][I]Efficiency:[/I][/B] Performance of a task with little or no wasted effort; capability to produce desired results with a minimum expenditure of energy. [B][I]Inefficient:[/I][/B] Wasteful of energy in performing a task; or underpowered and therefore incapable of performing a task to optimal standards. [/QUOTE]
