Tools & References

Handy tools and references for the Long Gong shooter. (External calculators open in a new tab; we don’t control them.)

Ballistics

• A rimfire-aware ballistic solver (look for one that supports the RA4 drag model) — see our long-range prep guide for why that matters.
• Chronograph your match ammo and track ES and SD — the two numbers that hold your vertical at distance.

Setup guides

• Choosing a scope rail · Headspacing · Torque & bedding
