I have a new patented resizing die that was recently advertised in the top 10 shooting magazines. With this die, you can now get up to 20 reloadings from your belted magnum cases instead of just 2 or 3 times. You can see it on a web site that we devoted to this one product. Take a look at www.larrywillis.com
and you can also read the article that I wrore about it for Precision Shooting magazine (Feb issue).
