Makes Everything Consistent!
I bought the Sinclair expander mandrel die, and then realized they were sold out of the 6.5 expander mandrels. I was lucky enough to come upon PMA Tool, as I wonder if this product is actually better. I'm using this during my 260 case prep, and I'm doing all my case prep on a Dillon 550. I have this located on station 4 of my Dillon, which is right after I Full Length Re-size, plus use a neck bushing. Since adding the neck expander mandrel to my process, my seating depths EXTREMELY consistent from case to case, as well as the pressure required to seat a round. Not only that, but across the chronograph, I had an SD of about 5fps, and an ES of about 12. Great product!
