I can’t remember where I saw them, but basically it was a little box with lots of little plastic tubes with lids that you could fill and label with your powder charges to make reloading at the range easy (no trying to throw and weigh powder in the wind outdoors).
Have you seen them? Do you know what Im talking about? Am I crazy and they don’t exist???
I have some older firearms where load data doesn’t exist for a lot of powders, and instead of loading up several dozen complete cartridges on the very very low end and having to either shoot them all or skip a lot and then pull bullets at home, I can just pack their charges, take a handful of cases and use a portable press like the handheld Lee reloader with my two dies, some primers and bullets.
If you haven’t seen these, can you think of a way to safely carry a couple of dozen pre weighed charges to the range?
