The searchable reference for firearms, ammunition, and ballistics data. Built by a shooter, not a media company.
Cartridges and powders. Results labeled by type.
Data sourced from SAAMI, CIP, Hodgdon, and manufacturer specifications.
Every tool cross-links to the others. Looking up a cartridge surfaces loads, powders, ballistics, and chambered firearms — not a dead-end description.
Specs, history, alternate names, military use, production status, and firearms chambered in each cartridge. 472 records with full ballistic data.
25,001 commercial loads. Filter by cartridge, manufacturer, bullet weight, velocity, and intended use.
252 powders with burn rate rank, grain shape, manufacturer, and typical cartridge references. Each caliber chip links to ballistic compare.
Side-by-side trajectory, drop, recoil, and energy comparisons. G1 ballistic engine. Rifle, handgun, and shotgun modes. Up to 4 loads at once.
4,638 active matches on a live map. USPSA, PRS, IDPA, 3-Gun, clay sports, and more. Filter by discipline, distance, and date.
Sourced charge tables: cartridge → bullet weight → powder → min/max charge → estimated velocity. Attributed to published manuals.
A search for .308 should not stop at a description. It should lead to loads, ballistics, powders, compatible rifles, reloading data, and ammo prices. Every page on this site connects to the others.
That is the difference between a reference site and a reference tool.
The private app for your own firearms records. Your guns, ammo, optics, range sessions, and maintenance logs — separate from the public reference tools.
Not standalone tools. Each one connects back to cartridges, loads, and powders — one dataset, more ways in.
Cartridge + bullet weight + powder → sourced min/max charge tables, attributed to published manuals. The question people search thousands of times a month with nowhere good to go.
Suppressors, NFA items, carry permits, mag limits, constitutional carry, castle doctrine, straight-wall hunting zones. 50 states, sourced, with correction submissions.
Live shipped cost-per-round for common calibers, historical percentile context, and email alerts when a cartridge drops below your threshold.
10,002 models in the database. Each page connects to chambered cartridges, factory loads, compatible optics, manuals, and Vault tracking.
Plain-English answers to the questions people actually type: Can I use 5.56 in a .223 chamber? Can I hunt deer with .223 in Pennsylvania? Short answer, technical depth, state notes.
Clean, filterable catalog websites for gun dealers. Caliber and ammo filtering that actually works because it runs on Lindcott reference data.
Submit corrections, missing cartridges, loads, laws, or feature ideas. Every submission is reviewed.
