A comprehensive collection of interactive, online ballistics calculators! Exterior Ballistics, Recoil Calculator, Wound Channel Calculator, Stopping Power Calculators (mutiple), Round Ball Weight Calculator, Powder Calculators, and more! A one-stop resource for your technical ballistic data needs.
>> Permanent Wound Channel
Marshall's adaptation and refinement of a formula to quantitatively calculate the permanent wound channel potential of any load utilizing a bullet with a relatively flat frontal area. This calculator generates its results by utilizing the meplat diameter (in inches) of a projectile and the striking velocity of that bullet to give an outstandingly concise calculation of the true permanent wound channel left by the bullet in live targets.
>> Relative Penetration Calculator
Another Beartooth Exlusive found only here! Generates the relative penetration index for any given bullet. Calculates based on bullet weight and Meplat or fronal area of the bullet. A great tool for comparing the potential penetration of one bullet to another.
>> Thornily Relative Stopping Power
Peter Thorniley designed this formula years ago. While hunting extensively both in North America and Africa he did practical field testing on numerous kinds of game animals. Living on the family orchard, he perfected this formula by continued field testing while conducting extensive depredation work. It calculates via a relative stopping power quotient the amount of gun and load necessary to cleanly take a game animal under all conditions. A great tool for comparison of one load to another, as well as the potential of one cartridge to another.
>> Taylor Knock Out Power (KO)
John (Pondoro) Taylor Knock Out Power has been respected over the years as a great comparison of two cartridges, one to another.
>> Foot-Pounds Energy Calculator
Figure foot-pounds energy of a load.
>> Recoil Calculator
Ever wonder how much kick a gun has? How fast it comes back at you? This calculator figures the velocity in fps of how fast the gun comes back at you, as well as how many foot-pounds are traveling with it!
>> Ballistic Coefficient (BC) Calculator
Want to figure the BC's for a bullet? This calculator will do the long equation figuring for you! Maximize before use.
>> External Ballistics Calculator
Figure the ballistics on a bullet/load combination! Includes bullet drop, lead, and more. Maximize before use.
>> Loads per Pound of Powder
Calculate how many loads you're going to get out of that new pound of powder.
>> Sectional Density Calculator
Calculate the sectional density of your bullet. (Proportion of length to width)
>> Cost per Load/Box Calculator
Calculate how much it costs to load your own! Figure either per load or per box! Includes primers, powder, bullets, and more! Maximize for viewing.
>> Powder Burning Rate Chart
Lists 110 of today's available canister propellants. Helps to get an idea of how fast or slow a given powder really is. Also available in PDF format. Click Here for PDF. Maximize for viewing.
>> Round Ball Calculator
Calculate the weight of a round ball by entering it's diameter! You can choose from four common alloys- Wheel Weights, Linotype, Pure Lead, or 1-10!
