About this model

IMPORTANT: Get the latest updates for this model here on PrusaPrinters. In 2021, all updates and uploads of new models were moved to PrusaPrinters, of course still free and under the same conditions... :) Reloading primer flip/flipping trays. The flip tray comes in three sizes: 50, 100 and 125 mm (2", 4" and 5"). For reloading with standard primers the 100 mm tray is great (common used size), but reloading with Federal, the larger 125 mm comes in hand. And the 50 mm tray is mostly for fun... >> If you like it, please leave a like or a tip... :)
