Detailed Description

KPY Shotshell Ballistics Program Version 2.0

USB or CD-ROM

This Shotshell Ballistic Program had been developed to compare lethality and penetration for factory and custom shotshell loads.  

This unique ballistic program generates data for all shot materials, including steel, lead, and tungsten-based pellets. The user inputs the factors of shot size, material, initial velocity, temperature, and elevation to calculate down-range pellet performance along with pellet count. User can select velocity, distance, time, energy, energy density, or gel penetration to find the effective energy of a pellet.

An excellent tool for comparing factory loads of different materials to find the best load for your specific quarry/hunting trip or sporting event. It can also be used by reloaders to calculate the effect of higher and lower velocities, shotsize, and load changes. After calculation, the user can then name and save the load in a catalog. Several loads can be added for comparison and then saved to a local hard drive and recalled whenever you need to reference the data.


  • Shot types:  chilled lead, antimony lead, steel, bismuth, and varied types of tungsten pellets including Hevi Shot, STSS, and BPX.

CALCULATION DETAILS:


KPY Shotshell Ballistics calculates the downrange performance of shotgun pellets. In this modern age, there are dozens of different shot types including chilled lead, antimony lead, steel, bismuth, and varied types of tungsten pellets including Hevi Shot, STSS, and BPX. All of these pellets also are loaded in shells with velocity ranges from 1000 to 1700 fps in loads from 1/2 to 2-1/2 oz payload. Many shooters and hunters have no way to compare the different types of loads to see which load is optimal for their shooting or hunting situation. KPY Shotshell Ballistics incorporates muzzle velocity, pellet size, and pellet material to calculate the downrange velocity at all distances and yields energy, energy density, and gel penetration for the load.

 

Energy (ft lbs) output is kinetic energy of your pellet. This is the most simple form of energy of the pellet with mass and the velocity. Certain energy values correspond with the ability of the pellet to break a clay target or kill a bird. For target shooters, they typically want to see a minimum of .3 ft-lbs of energy to break clay targets while many recommend 1.5 ft-lbs for duck and pheasant sized game. Energy Density (ft lbs/in2) is the energy of a pellet divided by the cross sectional area of the pellet. This parameter gives an additional parameter of incorporating the pellet diameter with the energy to take into account wound channel and impact shock. USFW did a study where they shot 4400 mallards at controlled conditions with steel, copper, and lead and found an energy density of 235 ft-lbs/in2 had enough penetration to kill a mallard size duck more than 95% of time. The most common parameter used evaluate downrange performance is gel penetration. Ballistics gelatin mimics tissue and muscle and is commonly used to evaluate lethality of all types of projectiles from handguns, rifles, and shotguns. The gel penetration output of KPY Shotshell Ballistics is the predicted penetration in 20% ballistics gel. Common values for penetration are .2" for clay targets, .5" for dove, 1.5" for duck and pheasant sized game, and 2.5" for goose-sized game.

 

Shotgunners that use KPY Shotshell ballistics are able to enter their exact custom loads specifications into the program and then see what parameters match field performance. They can choose energy, energy density, or penetration to evaluate and decide for themselves which velocity, shot size, and pellet type offers them the most competitive advantage on the range or in the field. Some interesting patterns begin to emerge as users evaluate the different types of loads. Higher density shot types allow for smaller shot sizes. Smaller shot sizes allow shooters to maintain pellet count of patterns while using lower payloads with lower recoil. For instance, if using 18g/cc density shot, a shooter with a 410 load of 1/2oz of TSS #9s, has the same penetration as a 12ga 2oz load of steel #BB shot and has 35 extra pellets in the pattern. This information is what has led to the explosion of using sub gauge shotguns in turkey and waterfowl hunting. The options for different loads are endless and a ballistic program will help you navigate through those options much faster and easier.
