This is a simple bleacher style loading block. The bleacher, or stairway, style makes it easier to get an overview compared to a flat loading block and allow for easier handling. I've uploaded two profiles - one for 50 cartridges and one for 25 cartridges (as the 50 crt does not fit on the A1 mini plate). One, or many, loading block is a must have on your reloading bench and printing your own is rather cheap compared to buying them.
