Bridge Type .223 Ammo Reloading Tray

thingiverse

I have different kinds of retail ammo loading trays, most of which are meant to be universal, and while they tend to work for most rifle loads I use, they're big and bulky and take up lots of space on the loading bench. I also found that once in awhile I lose track of where I am when I'm loading ladders and it forces me to count groups of cartridges so I know where on the ladder I am and what weight of powder I'm charging. This was inspired by the bleacher type trays I've seen here and there because I wanted to make something somewhat compact, but also needed to make sure I could reach each casing and not risk fumbling with my fat fingers. So I came up with the following requirements. 1) Because I'm wanting to keep track of ladders by round, I want each row and column marked by coordinates (in this case LETTERS and NUMBERS) 2) Because I wanted to store these compact it needed to be small. I determined based on my ladder sizes that I could make them hold 25 rounds each but stack them vertically when not in use. I printed 5 of them which lets me run them out 125 at a time if I want. So this is what I came up with. They're basically bridge shaped blocks that are stackable, small in form factor, terraced so case mouths are easy to reach, and marked on one side with letter and the other with numbers so as I go along I can catalog by row if grouping by 5 rounds or by coordinate if I want to do 3 round groups or whatever I choose. This has made loading ladders easier to keep track of and the trays are compact enough where they're smaller than pretty much any die case. (85Wx84.5Lx30H millimeters). They also make cases easier to grab just like on the bleacher type trays. This one is marked as .223 Remington (5.56 NATO) or 300 AAC Blackout/Whisper. It should comfortably hold any caliber casing that would fit in an AR15 with a standard bolt. I'll eventually make one for the .308 Winchester/6.5 Creedmoor group of cartridges but just this for now.
