Description: BLKDope is a precision ballistic calculator built specifically for .300 Blackout shooters. Calculate trajectories for both supersonic and subsonic loads side by side, with real-time environmental corrections powered by Apple Weather. Features: Compare two loads simultaneously — any combination of supersonic and subsonic G1 and G7 drag models with independent selection per round Miller stability factor and Litz spin drift calculations when bullet length is entered Interactive trajectory chart with pinch-to-zoom, drag-to-pan, and spin drift overlay Detailed dope table with drop, MOA corrections, velocity, energy, and spin drift Factory ammo library — 64 loads from 14 manufacturers with bullet lengths included, ready to load and calculate Save and manage custom load presets Real-time weather integration: temperature, pressure, humidity, and altitude from your location Exportable dope card PDF with full ballistic data Dark mode support Designed for accessibility with full VoiceOver support How it works: Enter your load data (bullet weight, ballistic coefficient, muzzle velocity, drag model), set your zero distance and sight height, and tap Calculate. BLKDope runs a physics-based trajectory simulation and gives you drop, MOA adjustments, velocity, and energy at every yard. Add bullet length to unlock stability factor and spin drift data. Pull live weather from your location or enter conditions manually. Weather data provided by Apple Weather.
