Expander Mandrel
Just Amazing, This mandrel is well made and very smooth and precise. I have used many mandrels in my day and shoot benchrest. This is by far the BEST! Buy the die which allows it to float, as it should, so you do not over work the brass

Great tool for my need!
I was having trouble finding 7mm BR brass, so with this tool I changed 6mm BR brass to 7mm. Glad I bought it.
