[QUOTE="MrBallistic, post: 432317, member: 20121"] Mikecr has the best idea. Taper expand out to a larger caliber, then set the sizing die off the shellholder a turn or two and size (turn down a little and check) just enough till the bolt closes with light resistance. This will keep the primers flush and give the best case life. You should be able to (temporarily) install the tapered expander in a size die any time you need to make cases, then replace with standard one during reloading. Additionally, P.O. chambered his improved cartridges, not to headspace on a factory round, but rather to "crush" fit at the neck/shoulder junction. The result would be that the factory cartridge would "blow out" the shoulder while the head remained against the bolt face. Fire forming can be an effective tool, but with so many versions of his improved exist today you really need to find a knowledgeable gunsmith to set these up correctly. [/QUOTE]
