Overview
F-Class Simulator is an interactive 3D shooting simulator that recreates the experience of long-range F-Class competition shooting. Practice reading wind, managing ballistics, and making precise shots at standard F-Class distances from 300 to 1000 yards.
Controls
Spotting Scope (Left):
- WASD keys: Pan and tilt the scope view
- E key: Increase magnification
- Q key: Decrease magnification
- Range: 2x to 100x magnification
Rifle Scope (Right):
- Arrow keys: Adjust aim point (0.1 MOA increments)
- +/= keys: Zoom in (decrease field of view)
- -/_ keys: Zoom out (increase field of view)
- Crosshair shows current aim point
Firing:
- Space bar: Fire a shot
- Each shot is recorded and scored automatically
- HUD shows current score and dropped points (points missed)
- Match completes after 60 shots (standard F-Class match)
F-Class Competition
Standard Distances: 300, 500, 600, 800, 900, and 1000 yards
Target Types: NRA F-Class targets (MR63-FCA, MR65-FCA, MR1-FCA, LR-FCA) are automatically selected based on distance
Scoring: Standard NRA scoring with 10-ring (X-ring) precision. Shots are scored based on impact position, with bullet diameter affecting line-breaking decisions
Match Format: 60-shot F-Class match (standard competition format). HUD displays current score, dropped points (points missed), and shot count
Dropped Points: Shows how many points you've missed (10 - score for each shot) and how many X-rings you've missed (1 - X for each X)
Ballistic Parameters
BC (Ballistic Coefficient): Measures aerodynamic efficiency. Higher values = less wind drift and drop. Range: 0.001-1.0
Drag Function: G7 recommended for modern boat-tail bullets, G1 for flat-base or older projectiles
MV (Muzzle Velocity): Initial bullet velocity in fps. Critical for trajectory and time-of-flight
Diameter: Bullet caliber in inches. Affects line-breaking scoring rules
MV σ (Standard Deviation): Muzzle velocity variation in fps. Lower is better. Default: 7 fps
Accuracy (MOA): Rifle+shooter precision. 1 MOA ≈ 1 inch at 100 yards. Default: 0.25 MOA
Wind Reading
Wind Flags: Observe flag angle and flapping to estimate wind speed. Flags point in wind direction
Wind Presets: Select from Calm, LightBreeze, Moderate, Shear, Strong, or Variable conditions
Wind Effects: Wind causes horizontal (crossrange) drift. The effect increases with distance and time-of-flight
Strategy: Use the spotting scope to observe flags downrange. Adjust your aim point based on wind reading and previous shot impacts
HUD (Shot Statistics)
Shots: Total shots fired in current session
Score: Cumulative match score in "XXX-Yx" format (points-X count)
Last Shot: Most recent shot score (10, 9, 8, etc.) with X-ring indicator
MV: Actual muzzle velocity of last shot (includes random variation)
Impact V: Bullet velocity at target impact for last shot
Tips for Success
- Start with calm wind conditions to learn the basics
- Use the spotting scope to observe downrange conditions
- Watch the red shot marker to see your last impact
- Make small adjustments to your aim point (0.1" increments)
- Pay attention to wind flag behavior along the entire range
- Higher BC bullets drift less in the wind
- Lower MV standard deviation = more consistent impacts
- Practice at shorter distances before attempting 1000 yards
