Lindcott Armory is a connected firearms reference system. Not a blog. Not a media property. Not a social platform.
It's a searchable, cross-linked database of cartridges, powders, factory loads, firearm models, competition schedules, range locations, and ballistic tools — built to be the one place you can look something up and find everything that connects to it.
Look up a cartridge and see its full specification, pressure data, chambered firearms, compatible powders, available factory loads with velocity and ballistic data, historical military use, and relevant competitions where it's commonly used. That's the idea: cross-linking, not isolated records.
Looking up a cartridge today sends you across Wikipedia for history, ammo.com for a load list, the manufacturer's PDF for spec data, Hodgdon's site for reloading data, and three different forum threads that contradict each other on pressure limits. None of those sources link to each other.
The same problem exists for powders, firearms, and competition data. Everything is siloed. If you want to know which powders work well for 6.5 Creedmoor, which factory loads are available for it, what firearms are chambered in it, and what trajectory looks like at 500 yards — that information exists, but not in one place, and not linked together.
This site is that one place.
Reference tools include: ballistic trajectory comparison (up to 4 loads at once, G1 point-mass model), powder burn rate chart, hunting cartridge guide (33 huntable species), military service weapon timeline, competition finder with a map and calendar view, and individual pages for every cartridge and powder in the database.
Lindcott Armory was built by a shooter, collector, and reloader based in Wyoming. The site grew out of a personal frustration: no single reference existed that connected cartridge data to factory loads, powders, chambered firearms, and ballistics in a way that was both accurate and actually searchable.
The data standards reflect how a serious shooter actually uses reference information — the difference between a SAAMI-measured PSI and a NATO PSI matters if you're loading for a chamber that was rated to one spec. Burn rate proximity does not mean charge weight substitution. An "estimated" BC is not the same as a published one. These distinctions are built into the data model, not treated as footnotes.
Questions or corrections: support@lindcottarmory.com
Cartridge specifications come from SAAMI for US commercial cartridges, CIP for European cartridges, and NATO STANAG documentation for military rounds. Manufacturer technical specifications and historical reference texts cover obsolete cartridges not standardized by either body.
Powder data is sourced from manufacturer published data sheets and official reloading manuals — Hodgdon, Lyman, Sierra, Hornady, Nosler. Burn-rate positions that cannot be confirmed from a primary source are marked as estimated.
Factory load data is sourced from manufacturer product catalogs and retailer data. Calculated fields — muzzle energy, ballistic trajectories — are labeled as calculated, not measured. Where a BC value is not published by the manufacturer, the field is left blank rather than estimated.
Competition data is sourced from USPSA, IDPA, ATA, NSCA, and SASS match databases, scraped and updated on a rolling basis. Range and location data is sourced from ATF FFL records and public records.
Where data conflicts between sources, we follow a defined source hierarchy. That hierarchy, and the rules for how calculated fields work, are documented on the methodology page.
Calculated fields are labeled. Estimated values are noted as estimated. Where SAAMI and CIP data conflict for the same cartridge — because they use different measurement methods — both values are shown and the standard is noted. We do not silently choose one.
User-submitted corrections are reviewed against primary sources before any record is changed. If a correction is confirmed, the source note is updated along with the value. If a correction is disputed — meaning two primary sources give different numbers — we note the conflict in the record rather than picking a side.
More detail on sourcing, measurement standards, and the safety limitations of ballistic calculations is on the data methodology page.
Lindcott Armory also includes a private vault app for tracking your own guns, ammo lots, sessions, maintenance schedules, and optics. The reference site and the app share the same database backend, but they are separate products with separate purposes: the reference site is public and contains no user data; the app is private and contains only your data.
The app is available as a progressive web app and native iOS/Android app. Details at /app.
