[QUOTE="wonderman4, post: 1796862, member: 72101"] Most rifle brass will not expand with pressures less than 12k psi loads. One thing I won't do is use COW or cornmeal in a good barrel. My universal load for fire forming is 10-13 grains of Red Dot with a nominal weight cast bullet for 30 caliber and up. It exceeds the pressure requirement to expand the brass. I am not sure of a charge for less than 30 caliber since the only thing I have fire formed has been 30 or greater. Another thing I do is to keep the cartridges bullet up to insure the powder stays close to the primer. Sometimes depending on the cartridge you may have to create a false shoulder, or just jam the cast bullet into the lands to keep it against the bolt face for proper forming. [/QUOTE]
