PFM Ballistics

From Corridor Enterprises LLC:

Highly accurate small arms ballistics calculator based on the 3 degree of freedom point mass system of differential equations as described by Robert L. McCoy in Modern Exterior Ballistics, along with the most common standard drag functions (G1, G2, G5, G6, G7, G8) measured at the Ballistics Research Laboratories (BRL) at Aberdeen Proving Grounds, MD.PFM Ballistics matches the results of the most expensive ballistics calculators and puts their proven accuracy directly in the palm of your hand. It is designed around the same equations and numerical integrations used by calculators that cost 10 to 20 times the price.- 1540 (and growing!) factory cartridges for you to choose from, or create as many hand-loads as you like!- G7 BC's are used where appropriate/available- Create and save your own scope and firearm "profiles" - Ability to use G1, G2, G5, G6, G7, and G8 coefficients- Several military rounds included (M855, SS109, M118, M80, M852), and we will be adding many more as we obtain info- Graph, table, and firing solution output- Output and most inputs in metric and imperial units (let us know if you would like to see more and we will add it!)- Calculates spin drift and Coriolis/Eotvos Effects (Bullet lengths are necessary to approximate spin drift. We are updating our database as fast as we obtain bullet length info. For some rounds, spin drift will not be calculated)- Ability to use the ISA/ICAO standard atmosphere based on elevation only (or use temp, absolute pressure, and RH for a more precise air density)- 3000 meter range- RK4 numerical integration w/ a 0.00005 second time stepUser Manual coming soon!To add a rifle, scope, or cartridge, press menu on the corresponding Equipment List Screen.To delete a rifle, scope, or cartridge, press and hold the rifle, scope, or cartridge you wish to delete on the corresponding Equipment List Screen.Planned updates include:* Kestrel Support* GPS Location* Accelerometer-based Target/Line of Sight Angle* Online Data Backup* G7 Cartridge/Bullet Database Additions* Additional Calculators* Muzzle Velocity Correction* Scope Calibration* Much more!Recent changes:v1.2.4:- Added muzzle velocity adjustment option for factory ammo- Fixed meter conversion error in firing solution target distance.- Raised graph resolution to 1 yard.- Forced numeric input for scope height and scope offset fields to avoid parse errors in calculations.Content rating: Everyone
