Simple 150 round loading block for 308 bolt face cartridges. Each hole is 10mm deep and holds more snug than other types of loading blocks. Print in PLA Marble for a beautiful finish.

Pauses have been inserted at the relevant layers to insert 6mmx3mm circular magnets in each corner near the top layers and near the bottom layers. The model takes 8 magnets total. Magnets get fully printed into the model and hold the trays together as shown. Note: the magnets are not overly strong and can easily be left out. They will not hold the trays together when tilted a ways.

I recommend printing and using my Magnet Polarity tool to install the magnets. Use the same polarity (+ or -) for all 8 magnets.
