Yeah, it's $59.95 + shipping and version 6 is now out. You can find it a lot cheaper on ebay or amazon. Disclaimer: I haven't seen or used it.Sierra Infinity 5
Infinity is an exterior ballistics program for small arms.
Infinity Suite includes the Infinity exterior ballistics program, additional Reloading Data programs to calculate all the cartridge and reloading data included in the 5th Edition printed manuals, and the Reference materials from the 5th Edition printed manuals.
Infinity is the fifth version of the Sierra Bullets exterior ballistics program. We believe you will find this to be the most complete and user friendly ballistics program available. This software program computes all essential elements of the trajectory, in 1 yard (or meter) increments, of any bullet that has a Ballistic Coefficient referenced to the "G1" drag function, and for any set of firing conditions.
These firing conditions include muzzle velocity of the bullet, elevation (or depression) angle of the gun barrel, altitude of the firing point, wind conditions at that location, and weather (meteorological) conditions at the firing time.
The trajectory parameters calculated by the program include velocity, energy, momentum, drop relative to the extended bore line of the gun, bullet path height relative to the line of sight of the shooter, wind deflection of the bullet, and time of flight of the bullet. All are computed versus distance from the muzzle as the bullet flies downrange.
The program outputs a list of all these parameters and provides graphs, which the user can select, of velocity, energy, drop, bullet path height, and crosswind drift.
But I don't really use it.....
PointBlank has several ballistic calculators and facts I don't keep in my log book. And I backup all my data on USB memory cards.(and also keep the log book).I'm a noob at reloading, but I've just been using a spiral notebook to record the case length, powder, charge, bullet weight and Manufacturer, the OAL and comments on the reload. That way I have an entire sheet of paper dedicated to that particular reload.
I guess that is OK? Didn't know there was software, but since I've been through about 6 different computers....the others crashed, the batteries failed to charge and were unavailable, the screen separateded from the laptop keyboard (DELL), the Hard Drive took a crap and nothing was recoverable, soooooo; I use paper.
