Most software wants you to feel good. It rounds off the uncertainty, calls a three-shot group a result, and shows you a confident number without ever admitting how little it actually knows. Then it puts that behind an account and a subscription and a cloud you don’t control.
veg.tools is built the other way around.
The first tool out of the workshop is Vegan’s Loadbook — a companion for precision handloaders, the people who chronograph their ammunition and chase single-digit standard deviations. It does two jobs, and keeps them strictly apart:
- It predicts what a load should do — velocity, pressure, and the full trajectory — and every number it gives you carries an interval and a grade, so you know how much to trust it.
- It referees what your ammunition actually did — honest statistics over your chronograph data that tell you whether a difference is real or just noise, instead of flattering a small sample.
The one rule the software will never break is the one the name of this post is about: it is a referee, not a cheerleader. It never tells you a load is safe — because a model genuinely cannot know your firearm, your brass, or your lot of powder. Pressure shows up only as a percentage of the SAAMI maximum, and being under that line is shown neutrally, never green. That isn’t a disclaimer formality; it’s the whole design.
Everything is local-first: your data lives on your device, syncs over your own network or a folder you choose, and exports to plain files any time. No account, no tracking, nothing farmed from you. (Yes — the software is 100% vegan.)
If you want the honest, unglamorous version of how it all works — why we combine interior and exterior ballistics, what a drag function really is, how a bullet actually flies, and why five shots aren’t enough to know your standard deviation — that’s what The Science is for. No other tool bothers to explain it. We think that’s exactly backwards.
More soon.
