IBC for AI agents — beta

Beta · free during the beta period · comparison tool, not a load table

IBC is a physics-based interior-ballistics calculator. This page lets your AI coding agent (Claude Code, Cursor, or any MCP client) call the same solver the website uses — with the same safety envelope on every result.

Free during the beta. Each beta key gets 100 engine calls per day while the beta lasts. When the beta ends we will say so here before anything changes.

What your agent can do

• Solve — modeled velocity, energy, and pressure-position for an exact cartridge + bullet + powder + charge, with the full safety envelope.
• Work-up ladder — a charge ladder from a published-reference or charge-only starting point, at least five rungs, per-rung numbers.
• Trajectory — a point-mass drop table fed by the modeled muzzle velocity (beta keys get the table out to 300 yards).
• Component lookups — cartridge specs and propellant listings from the served database (identification only, never load data).

Every result carries a non-removable safety notice: this is modeling output, not published load data. Cross-check against published data for your exact components before loading anything, start low, and work up.

Step 1 — request a free beta key

Enter your email; we send one key to that address (shown once in the email, so store it when it arrives). One key per address while you are in the beta; ask again if you lose it and we will sort it out.

Step 2 — connect your agent

Paste this into your MCP client configuration and put your key where it says <your key>:

{
  "mcpServers": {
    "ibc-ballistics": {
      "url": "https://reloadingcalc.com/mcp",
      "headers": {
        "Authorization": "Bearer <your key>"
      }
    }
  }
}

In Claude Code you can also run:
claude mcp add --transport http ibc-ballistics https://reloadingcalc.com/mcp --header "Authorization: Bearer <your key>"

Measured, not marketed

The engine grades itself against published load data: 30,327 printed loads at launch, average velocity error about 7.5%, worst powders included in the public table. If your agent makes a claim, the methodology and the accuracy paper show where that number came from. Most tools in this space publish nothing.

Questions

Everything the agent sees comes from the same engine and the same safety contract as the website; the methodology and accuracy page covers what the model is good for and where it errs. Problems or feedback: reply to the key email.
