How do you guys organize ammo when testing?

KCode · 2025-06-17T16:22:22-0400

If any of you guys ever go to the range testing ammo in say 5 shot groups each, how do you organize and transport it? Are there any boxes or containers that make it easy to store the ammo and maybe notes of what the loads are?

I've been using ziplock bags but it seems like there could be a better way I don't know of

Really? Mtm 50 round boxes. Each charge weight gets a 5 round column. Sharpie across the lid the test parameters.

I save the plastic inserts from factory ammo. Print a label or write on them with a sharpie.

MTM Cases
I just write down the loads in groups of 5 on a post it and slip it in the MTM

I use painters tape and label each row.

I have 50 and 100 round cartridge boxes that I organize my cases in for load development and put corresponding labels (usually writing on some narrow masking tape for reference), like this:

I also number the cartridges.
Some days, shit happens and things get dumped over

Write the load with the sharpie on the front case in the box.

That's such a good idea! I know it isn't specific to that case, but what brand case is that? I can't tell.

It came with the cases I ordered from Peterson Cartridge. On their website, you can order just the cartridge boxes by themselves.

Well those wont work, I need something for 44 cal

Mike Casselton · 2025-06-17T21:09:00-0400

MTM, J&J and a host of other companies make 50-100 round plastic cartridge boxes

I use MTM cases. I write down the load info on tape like others above and also have my rounds numbered by sharpie just in case something gets out of order or gets dumped.

waveslayer · 2025-06-18T00:49:54-0400

Sharpie on brass, group 1 all get a 1 on them, group2, a 2, etc.. simple yet effective

This but using a label maker instead of a sharpie.

I do the same but sharpie directly on the rounds in the example of a ladder.

MTM and I just put an index card with the layout in the box. IME, no need to complicate it more than that.

same but I scotch tape the index card to the lid - ask me why lol

Each case is numbered with the group and the load.

I take a photo of case in front of the machine with the load punched in for that set. That way I can always doublecheck my actual load.

This allows me to always doublecheck and to inspect case and primers at home.

Labeling them individually like that is a very good way to keep track of the cartridges being ejected onto the ground or when firing a semi, then when they're collected, you've got a way for which case did what . . . like if one wants to align chrono numbers to each case.

Since I only load for bolt guns, my style is to eject the cases directly into my hand and place them exactly where they came from in the cartridge box. I can still keep track of the details for each cartridge, but without all that work of labeling each of them.

But. . . from time to time I do find myself labeling a few individual cartridges that have unique traits when I'm experimenting around.
