You can filter the selection with the following flags:

-w    Bullet weight, in grains (example: "120")
-b    Bullet model name (example: "Ballistic Tip")
-m    Bullet manufacturer (example: "Lapua")

Sub-commands

cartridges    List all avaliable cartridges
manufacturers List all available bullet manufacturers (with VV typos and all)
bullets       List all available bullet models

Reloading data

It comes with reloading data bundled. You can however chose to download new data and use that for display. That is triggered by the -d flag:

vvrl -d -m Barnes -w 127 "6,5 Creedmoor"

Note that this data is currently not stored, so you need to use the -d flag to always get the current VV data.

Updating bundled reloading data

It is certainly possible to update the bundled reloading data so you don't have to use the -dflag all the time.. Upon build, the rldata.json file is embedded in the executable.

You can replace that rldata.json file with new contents you download from Vihtavuori and run go build or go install to build and/or install a new executable.
