Gun Number

Calling wind is the hardest part of long-range shooting. Gun Number trains the mental math precision shooters do under the pressure to develop a wind call before conditions change. 

Practice with realistic scenarios:
• Four difficulty tiers — from stated wind at full value (Novice) to multi-cue overlap with shifting wind across stages (Expert)
• Read mirage angle, environmental cues, and flag indicators with cue tables that match how shooters actually call wind
• Multi-target stages of 1 to 4 targets — single timer, like a real PRS troop line
• Bracket mode shows you a wind-speed range to compute, with a Send-it / Fits / Exceeds plate-fit check
• Configurable plate size from 0.5 to 3 MOA, custom MRAD if you want it
• Density altitude correction past 800 yards, baked into the math walkthrough
• Mirage drift direction matches your wind clock — every cue matches what you'd actually see downrange

Built for actual stage practice:
• Per-target timer that matches the pressure you'll feel between shots
• Self-rating after every reveal builds the data you need to spot weak spots
• Session summary breaks performance down by wind cue type — find what's costing you points

Educational reference built in:
• Worked examples that walk through the formula on real scenarios
• Clock-face wind angle diagram with multipliers
• Full cue tables for mirage, environmental, and flag indicators
• Density altitude correction reference
