The Magpul Core‚Ñ¢ Precision Rifle Data Book 2.0 uses a simplified density altitude-based, color-coded chart to record your rifles' data across a wide spectrum of shooting conditions. Using a rugged, all weather material that can be written on using map pens, pencils, and non-permanent markers, this data book was designed to perform in austere conditions. Recorded data can also be erased with alcohol-based substances so the book can be reused.
The Magpul Core‚Ñ¢ Precision Rifle Data Book 2.0 provides a true all-weather, semi rigid writing surface. Its pages are reusable and include a field expedient density altitude calculator, cold bore shot tracking log, known distance data confirmation pages, range cards, a point of impact shift tracker, and simple hasty hold formulas. Ring not included.
