The connected firearms reference
571 Cartridges.240 Powders.37,024 Factory Loads.
One searchable system for firearms, ammunition, and ballistics — where every cartridge connects to its loads, suitable powders, and the rifles chambered for it.

Cartridges and powders — results labeled by type.
Sourced from SAAMI, CIP, manufacturer specifications, and the ATF FFL registry.
Core tools

What makes it different
Wikipedia tells you what a cartridge is.
This connects what it does.
How it works
Connected answers, not dead-end articles.
A search for .308 shouldn't stop at a description. It should lead to loads, ballistics, powders, compatible rifles, reloading data, and prices. Every page here connects to the others.
That's the difference between a reference site and a reference tool.
The private side
Lindcott Armory Vault
The private app for your own firearms records — guns, ammo, optics, range sessions, and maintenance logs, kept separate from the public reference.
- Offline-first. Your data doesn't need a connection.
- No public collection display. No social feed around ownership.
- AI assistant with full vault context; maintenance alerts from round counts.
- Private by design. No ads, no data selling.
