Burn rate position shows where a powder sits on the fast-to-slow spectrum — useful for finding powders in the same neighborhood. Proximity does not imply safe substitution. Always use published load data for your exact cartridge, bullet, primer, and case combination. Never exceed published maximum charges.

Track your powder inventory in Lindcott Armory.

The website shows you burn rates and specs. The app lets you track what you actually have — pounds on the shelf, loads you've worked up, and the components that go with them.

◈

Component inventory

Log every can of powder, box of primers, and bag of bullets. See what you have at a glance — no spreadsheet required.

⊙

Batch tracking

Track lot numbers per component. If a batch causes issues, you'll know exactly which loads used it and when.

◻

Load recipes

Save your proven loads — powder, charge weight, bullet, primer, OAL — and link them to your session logs for velocity tracking over time.
