Edit your rifles, bulk-import your reloading components, and sharper accuracy throughout. - **Edit any rifle.** Tap the pencil on any rifle in My Armory to update its setup — barrel, twist, scope, reticle, loads, zero conditions, and more. Locked rifles stay protected. - **Bulk import & export for reloading components.** Have hundreds of powders, primers, bullets, or brass? Import your whole inventory from a spreadsheet instead of one lot at a time. Export any component tab to CSV, or download a blank template to fill in — right from the inventory screen. - **Tell us what to track.** Every Reloading screen now has a quick way to request a field or section you'd like added. - **Smarter DOPE widget.** The home-screen DOPE widget shows your holds in your scope's unit — MIL or MOA. - **Sharper and more reliable** across the calculator, rifle profiles, the reticle simulator, and the reloading suite.
