26cal. Expander Mandrel 6.5mm
Our Neck Expanding Mandrels are designed to fit both the 21st Century Shooting and Sinclair Expander Dies. Our mandrels are longer than other expanding mandrels and feature a special dual taper which expands both on the up and down stroke of the press to more uniformly expand and straighten case necks.
Expanding Mandrels are available in the following calibers:
17, 20, 22, 6mm, 25, 6.5mm, 270, 7mm, 30 and 338
Also available in our Neck-Up mandrels for 22cal – 6mm and 6mm – 30cal. Perfect for necking 220 Russian up to 6mm for PPC and 6BR up to 30 caliber for 30BR.

This mandrel is double tapered so you can feel it resizing the neck on the down and up stroke. Because of the feel you also don't tend to bottom out the mandrel base on the case bottom like the Sinclair's do because you have much better feel.
I am in the process of case forming using larger necks to smaller. Rather than ream the inside of the neck I have chosen to expand the inside to the desired dimension then neck turn for fit in chamber. These mandrels( I have them in 224, 264, and 308) go in expanding the case with no lose due to case collapse and extract easily. I have other brands that don't do so well.
I have put one of these in my reloading setup just prior to filling the case with powder. It provides more consistent neck tension as well as giving me notice that a case is too loose or too tight.
Every PMA tool I have purchased has been top rate. At least as important is service is exceptional too.
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!
