[QUOTE="abinok, post: 126499, member: 16"] Necking the case up one caliber, then back down to the origional caliber with a FL sizing die that is adjusted up out of the press, moving the neck-shoulder junction forward some amount. This amount should be about .010" longer than this dimension in the chamber. This causes the cartridge to headspace at this point instead of allowing the case to be slammed forward as far as the belt, then streached back as pressure builds. This is exactly how all of the ackley "improved" cartridges work... and if theres more than .020" differance case to chamber... its the ony way to go. Though honestly... im beginning to think its the only way to go regaurdless. Stuff required to neck your caliber up is yourFL die, and about $15 of other stuff, and its very simple. [/QUOTE]
