6mm ARC Loading Block

This is a reloading block that fits 6MM ARC (and should also fit 7.62x39, 6.5 Grendel, and others with the same case diameter). This is based on the aluminum reloading blocks sold by Lyman, and is the same length and width. There is also a through-hole at the bottom of each hole, which allows debris to fall through, and makes it easy to check for primers or flash hole obstructions by holding the tray up to light.
