I recently purchased Redding's taper crimp die for .30 Carbine. It came with no instructions, so I tried inserting the cartridge into the die where I had resistance in the final 1/2" of the downstroke on the RCBS press. The resulting cartridge had a decided ring around the case mouth that was pressed into the bullet, looking all the world like a roll crimp.
Sure enough 1/2 of them wouldn't fire out of either my Carbine or my Blackhawk, which is usually very unpicky. The obvious problem is that the rounds were seated too far into the chamber and the firing pin was unable to get a sufficient hit on the primer. The primers had very small, shallow dimples in them.
Anyone use these Redding taper crimp dies? How should they be used? How far into the die should the cartridge be inserted?
