Personal bests & milestones

Full completed strings only, compared within the same range, distance, rifle, activity and simulation version.

Practice milestones

100 practice XP for a full string, 50 for a full training session. Zero sessions earn a milestone. Awards update from saved results and corrections. These are game milestones, not an official shooting classification; they do not change ballistics or standings.

YOUR ACCOUNT

Keep your profile secure.

Your passkeys, recovery key and sessions all access the same saved profile.

Confirm your identity

Security changes require a recent sign-in.

Competition access

Practice and training are available with beta access. New reviewed competitions require a single-use ranked invitation or administrator approval. Restore your existing profile to keep the same access and event entries.

Open Refresh to check your status.

Reviewers use profile references, invitation history and your message. Sharing a household network does not exclude you. No new device fingerprints or IP history are collected for eligibility. Deletion removes your request and profile linkage; anonymous event reservations remain to prevent repeat entries.

Recovery

Store your backup key privately. Replacing it invalidates the old key and signs out other sessions.

Your data

Download your profile, settings, feedback and score history. Private replays remain available individually in your logbook after any event embargo ends.

Delete your profile

This permanently removes sign-in access, settings, feedback, practice history and private replays. Competition scores and bracket positions remain under “Deleted player” so other players’ results stay valid. Backup copies expire separately; deletion records must be reapplied during any recovery.

Private match data is removed in the background. Save your export first.

Ranked eligibility and invitations

Confirm the intended player before approving. One competition identity may have several profiles, with one approved ranked profile at a time. A shared beta code grants practice access only. Revocation stops new controlled entries and active shots; earlier results require a separate result review.

        THE FIRST STRING
      

      
Watch. Adjust. Commit.

      
    
        
  1. 
          Read the range. Flags show air movement; the meter measures only the firing line. Downrange
          conditions can differ.
        
    2. 
        
  2. 
          Watch the mirage. In Spot or Scope, select a near, middle or far layer. Heat shimmer drifts
          with the crosswind and boils when crosswind eases. Ground heating controls its visibility in
          practice.
        
    3. 
        
  3. Use your range card. Calm elevation is already dialled in. Windage is your call.
    4. 
        
  4. Fire two sighters. Check the electronic target and adjust elevation or windage.
    5. 
        
  5. 
          Shoot for record. Twenty shots, with a twenty-minute server clock. Unfired record shots count
          as misses.
        
    6. 
      

      

        Drag the scope view to move your aim. Use arrow keys for fine adjustments. Press Space or tap FIRE.
        You can return to the lobby and resume from your logbook; the clock keeps running.
      

      

        Daily events allow one attempt with the same .308 load for every player. Detailed trajectories unlock
        after the event closes. All locations are procedural interpretations, and the simulation is still
        being validated.

          Original game concept and prototype: Richard. Rifle artwork supplied by the WindCaller team,
          depicting the Savage 12 F/TR and Vortex Golden Eagle HD ECR-1. Rear support and range scenery are
          procedural assets.

          Rendering uses Three.js (MIT).
          Input validation uses Zod (MIT).
          Passkeys use

          Flags use an XPBD cloth approximation with gravity and aerodynamic drag. Fabric mass and response
          are declared simulation assumptions, awaiting real-flag calibration. Terrain grass is procedural,
          with a simplified bending response. Range layouts are interpretations, not surveys.
        

        

          The comparison lab lists load provenance and uncertainty. Published nominal data, numerical
          agreement and physical field validation are different forms of evidence. The game does not predict
          ammunition assembly or internal ballistics.
        

      

      

        Rifle and target timing
        

          New sessions use a five-second rifle cycle: three seconds to reload, then two to settle. This is
          game pacing, not a measured action speed. Flight happens at the same time. New Practice sessions and
          Training mark at impact; delivery also depends on your connection. Competition target timing follows
          the event rules, normally seven seconds after impact. Wait for both the rifle and target before
          firing again. Early input does not consume a shot. Saved sessions keep their original rules.

  1. Choose your setup. Select your optic and controls, then save.
    2. 
          
  2. 
            Zero in calm conditions. Keep aim and dials fixed for three shots, then save the
            group-centre correction.
          
    3. 
          
  3. 
            Read a steady crosswind. Compare flags, near/middle/far mirage and the local meter. Make an
            unaided call, then check the optional hold aid.
          
    4. 
          
  4. 
            Review and repeat. Inspect your shots in the logbook, then complete a practice string
            before competing.

Equipment comparison lab

      

        Compare existing presets in the same conditions. This separate exercise does not use an event's wind
        or affect your scores. Savage loads use nominal 24-inch test-barrel velocities; the displayed 30-inch
        rifle has no measured velocity profile yet.
