Understanding Firearm Ballistics: Robert A. I found this one a good read and nice starting point for many. If you are interested in your own development The advantage is that I can adjust anything for any load including retardation coeficients, meso variables, etc.īut this is not for everyone as you need to study and also learn excel.

I used a both a nomad platform with windows mobile and a Dell axim (poor mans solution) for my son. The math is not that complex to start but then the development can grow Long Gun Training just ran an external Ballistics lecture last weekend we addressed all the principles of this and showcased several programs.Ĭlick to expand.Over the years I coded my own in excel. Windows based programs have the ability to blue tooth kestrel meters and also cable in laser range finders for storing and indexing targets for quick recall and firing solutions. It can be done but involves time and effort. If you only shoot at the same range, your numbers will be easier to set, take your shooting down to sea leveland get numbers that work, then go into the mountains changing major presets substantially, you will have a little more work getting things calibrated, especially for long and extreme long range.

You also have to really test the results in different locations and atmospheric conditions. With different programs they treat inputs differently some do a great job, others the settings are abit tedious and time consuming. Also scope travel calibration is a variable that should be addressed. Now as I said already the key is to get your real world numbers into what the program calculates, this is done adjusting bullet BC, muzzle velocity, some programs have a DK factor or drag constant that can be adjusted to slide numbers in, but be careful with this one. On windows based and windows mobile systems, the two big ones on the market are Field Firing Solutions and Patagonia Cold Bore

On Android take a look at Applied Ballistics created by Bryan Litz. However, understand that this zone of bullet flight is still unpredictable.įor the phone point mass programs I would suggest on Iphones use Ballistic AE operating on JBM modified point mass. Pejsa program works better for long range and extreme long range, handling transonic bullet flight better. Pejsa program is a closed form solution that uses a BC value but then incorporates its own retardation coefficient function in order to model specific projectiles. They have the ability to run on simple hardware and many do a good job within the short to mid-range distances.

Point Mass programs are driven on using a fixed drag model(G-1 or G-7). Sometimes this is quick and easy other times it can be a challenge. Regardless of which Ballistic program you use the key is to get your real world data matched with what the program calculates.
