We just used a mouser type, and turned the top upside down. There is a flat on top and bottom, the barrels aren’t on very tight. Super cool action, great easy to tune trigger.
Couple of my favorites are a 20practical and a 6mm Grendel.
Awesome dies, I ended up with a extra set in a trade. These size to really nice dimensions and the forster seaters are my favorite.
Like new, guy loaded 30ish rounds
