Impact Ballistics vs Wind Reader

The TRACT Optics Impact Ballistics mobile application takes the guesswork out of long-range shooting and provides data to help the most experienced shooter as well as the beginner or novice. This mobile application is one of the most comprehensive databases of information available today. With virtually every modern ammunition manufacturer’s information listed shooters can match any TRACT rifle scope reticle to their exact cartridge. Simply select your scope, then your ammo/bullet the program will calculate the bullet drop information as it pertains to your reticle automatically. If you cannot find your particular round of ammunition in the program, simply add the Ballistic Coefficient (B.C.) and Muzzle Velocity to the program and you will be good to go. With the ability to import current weather conditions the Impact program will provide up to date Bullet Drop Compensation to help you make accurate shots in the field or at the range. While the mobile application is designed to provide ballistic date without an internet connection, when the user has an internet connection, they are able to access our complete library of videos, articles, and blogs. Simply navigate to the Learn section of the app and you can access the Getting Started section for Rifle Scopes, Binoculars and Spotting Scopes as well as Pro Shooting Tips with videos detailing How To videos showing how to maximize the performance of your optic. You can even shop our complete line of Optics and Accessories right from the App. This app will be continually updated with new ammunition information, new product releases and videos. Selectable options include Meters or Yards, Drag Table, Spin Drift, Sight Height, Printable Dope and BDC cards, the ability to compare loads, atmospheric conditions (manual entry or automatic import), wind direction, sight setting/zero calculator and much more. The program is capable of providing ballistic data out to 2,500 yards. The BDC card allows the shooter to print out a “cheat sheet” that can show the bullet drop at each magnification (for Second Focal Plane scopes) The Dope card provides velocity, energy, path, drop, wind drift, time of flight, # of click value and MOA or MRAD info in 5, 10, 25, 50 and 100 yard increments. Weather/Atmospheric conditions can be automatically imported thanks to our direct link to World Weather Online, or you can manually enter the Temperature, Altitude, Barometric Pressure and Humidity through the Conditions section. The conditions section also allows the user to enter Bullet Wind Drift information such as wind speed and direction and provide data in inches, MOA or MRAD. The sight settings section is a great resource for shooters who would like to zero their rifle at a further distance then they are able to shoot. For example, if a user only has access to a 100-yard range but would like his rifle to be zeroed at 200 yards, the Sight Setting section will show the user where his bullet needs to impact on a 100-yard target to be zeroed at 200 yards. Our goal for this app is that it provides you with a comprehensive resource for everything and anything related to TRACT Optics…Where you Belong.

Wind reading for long range shooting. This app uses the Eagleman Technique. The phone's inclination sensor is used to convert mirage and rain angles to wind speed. The Eagleman Technique was developed by James Eagleman in 1992 to provide real-time wind speed based on mirage/rain angles and percentages. The method has a US Patent. James Eagleman is the master instructor for the Barbour Creek Long Range School (http://barbourcreek.com).
