A 50 round reloading tray inspired by the ever popular Frankford Arsenal Perfect Fit reloading trays. This design is slightly different by allowing the neck of the cartridge to rest in it's own pocket, giving the cartridge more stability when placed in the tray upside down. The stackable design allows for convenient storage. This tray will also stack with the other reloading trays that I've designed!

.223 Rem/5.56x45 NATO, 300 AAC Blackout, and other cartridges that share similar case dimensions such as 17 Remington, 22 Hornet, 221 Remington, 222 Remington, and 30 M1 Carbine may fit in this reloading tray, though the recessed neck pocket may not work with all cartridges.

Print with PLA or some other filament with high dimensional stability/low shrink factor, and a decently tuned printer is highly advised, as the tolerances are fairly tight.
