Sierra Bullets Reloading Manual V6.0 of Rifle and Handgun Reloading Data. The development of this reloading manual app has brought exciting, new changes. Many new Sierra bullets have been added, with new cartridge types and powders. Sierra built its own Pressure Testing Lab to quantify the new loading data found within the app. App features include: Reloading powder weight calculator for all the cartridges found in Sierra Bullet's paper manual. History about most included cartridges. Bullet details for all of Sierra Bullet's current and many older bullets. Exterior Ballistic paper. Technical contact information. Answers to Frequently asked questions about reloading. Firearm care and maintenance information. Ability to view in dark or light mode for easy reading. The free version has a reduced amount of data so users may see a sample of how the program operates. A subscription in-app purchase includes more text for key sections of the app including The Bullets section, The Reloading Section, and the Ballistics section. The most important feature a subscription adds is the full set of current cartridge data for hundreds of cartridges. Sierra Bullets LLC is constantly adding more data as new bullets are developed, the app will be updated as new data is available. Sierra Bullets has been producing hard cover manuals for over 50 years but using an app allows more functionality for the user.
