Know the system.
Know the shot.
Product help, match craft, gear judgment, and practical ballistics—edited into one field library that can meet you wherever the question appears.
Start with what matters at the range
Three practical reads selected from the current field guide.
Build your first NRL22 FreeDOPE card
Turn the current matchbook into a compact, verified rimfire card without losing stage order, units, or revision identity.
Shoot your first NRL22 match
Move from finding a local match to arriving prepared, following the range commands, and learning from your first result.
Know what FreeDOPE can calculate—and what it cannot verify
Separate solver output from field truth so a precise-looking answer never outranks uncertain inputs or observation.

Task-focused help for FreeDOPE, match discovery, scoring, and running events. Guided tours remain attached where doing beats reading.
Matches
1 articleFind and register for a match
Search by date, discipline, and location, then confirm the registration state before you travel.
FreeDOPE
13 articlesMake your FreeDOPE workspace range ready
Confirm the profile, conditions, wind call, card, units, and accepted solution that will travel to the firing line.
Set up and verify a ballistic profile
Build the solver input for one exact rifle-and-ammunition configuration, save it locally, and verify a newly accepted solution.
Set environment conditions with a known source
Choose the atmosphere source FreeDOPE should trust, understand density-altitude and pressure authority, then accept a fresh solution.
Adjust and verify a FreeDOPE wind call
Apply a speed and clock direction, preview the effect across targets, and keep the call distinct from the atmospheric source.
Read elevation, wind, velocity, time of flight, and Mach
Use the Live HUD for the active target and the table to understand how the solution changes across the full card.
Build and verify a FreeDOPE card
Name the card, enter target distances, preserve its match source, and recalculate before using the resulting field calls.
Create, revise, and review a FreeDOPE course of fire
Attach a match document or paste stage text, preserve its revision, review every generated target, and deliberately adopt the accepted card.
Browse and activate saved FreeDOPE items
Switch among saved cards, profiles, and courses of fire while keeping the active workspace change explicit.
Print, export, and share FreeDOPE data
Choose the output that matches your recovery, analysis, device, or range-use need and verify its accepted source.
Back up, restore, and move a FreeDOPE workspace
Prepare for offline use, preserve a recoverable export, and verify identity and revisions when moving data between devices.
Manage profile identity and revisions
Keep rifles, ammunition lots, hardware changes, and experimental truing from collapsing into one ambiguous ballistic profile.
Resolve pending sync and workspace conflicts
Protect the accepted local workspace when another device, an offline edit, or delayed synchronization introduces a competing revision.
Track matchbook and course-of-fire revisions
Keep organizer corrections traceable from the source document through the reviewed FreeDOPE card and every field copy.
FreeDOPE fundamentals
13 articlesRecognize saved, solved, accepted, stale, and verified data
Know which workspace revision FreeDOPE preserved and calculated, which snapshot is active, and what still requires confirmation on the rifle.
Choose G1 or G7 without breaking the profile
Keep the ballistic coefficient paired with the drag model used by its source instead of treating BC as a standalone number.
Validate a ballistic profile at multiple distances
Use a near, middle, and farther observation to distinguish a useful profile from one that merely agrees at a single target.
Decide whether to true BC or muzzle velocity
Correct the uncertain input—not whichever number is easiest to change—and preserve the observation behind the decision.
Diagnose a ballistic curve that looks wrong
Check identity, units, zero, velocity, drag, conditions, and target data in an order that preserves useful evidence.
Use density altitude or station pressure correctly
Choose one clear atmospheric authority and avoid treating an altimeter setting as local station pressure.
Choose manual range data or airport weather
Judge an observation by location, elevation, age, terrain, and purpose instead of automatically choosing the nearest source.
Understand zero, offsets, and environmental shift
Keep mechanical zero, profile offsets, zero conditions, and observed environmental change conceptually separate.
Know what FreeDOPE can calculate—and what it cannot verify
Separate solver output from field truth so a precise-looking answer never outranks uncertain inputs or observation.
Keep distance and angular units consistent
Prevent silent yard-versus-meter and mil-versus-MOA mistakes when building, reading, printing, or sharing a FreeDOPE workspace.
Turn chronograph data into a defensible profile
Capture a representative velocity string, preserve its conditions and ammunition identity, then validate the resulting curve.
Build a wind bracket instead of one perfect call
Use multiple plausible wind speeds and directions to prepare a decision range for changing field conditions.
Log observations without overfitting the profile
Preserve impacts, conditions, and confidence so repeatable evidence can improve a profile without chasing isolated shots.
Match management
2 articlesCreate and publish a match
Build the match record, readiness details, registration, documents, and publication state in a deliberate order.
Prepare registration and squadding
Check capacity, eligibility, squad assignments, documents, and participant communication before match day.
Scoring
1 articleResolve scoring imports and corrections
Identify the authoritative score revision, preserve evidence, and publish a correction without losing the original.
Operations
