Thread: Fill length resizing not using expander button.

I mate of mine wasted 2 sets of Hornady dies and fkd up 10 lapua magnum cases because it worked the necks too hard and no matter how much carbon lube he used on the inside of the necks. Expander ball just can’t pull out. I have had the same experience with most Lapua cases (hard to pull expander ball out) as they usually have thicker wall. So to accommodate all types brass makes, now I set up most of my resizing with redding bushing dies and expander mandrel. You can change the bushing to decide how much to work the brass and precision resize different thickness of brass to achieve desired neck tension. Bit more procedures. You don’t need to use the expander ball that comes with the die. You can use different size expander die and mandrel to open up the necks to difference sizes for your bullets to seat in with the neck tension you want. Again lots of fun (fk arnd).
