After seeing many arguments about what caliber was better, or which design was better I decided to make my own model to show the difference between different rounds. I take into account such data as Sectional Density and Momentum and then scale it using my own model. I didn't use kinetic energy or other variables because there's no guarantee that a rounds kinetic energy will be dumped into a target. We do know however that the Sectional Density of the round will come into play. We also know that momentum is another variable that does work if a round hits a target.

So, why do we need this? Well, lets equate this to a cars engine. Engines have specifications a lot like ammunition. Bore diameter, stroke, fuel for the explosion. Instead of listing a car by it's internal engine specifications, they list it by Horsepower. Well, that's exactly what I want to do. Have an easy Horsepower number for ammunition. Many other people have made their own models, and they're confusing. They either give you a very small number like 2 or 3, or they give you just the sectional density, which could be .84. These aren't very good numbers to work with, and this is why my model is superior.

Legend: caliber should be in inches, i.e. .429; weight should be in grains, i.e. 300; velocity should be in feet per second, i.e. 1000.
