Make sure the decapping pin protrudes from the die only 3/16", and center it as well as possible. The more it sticks out, the more likely it will miss the hole and break when the hole is slightly off center. I got this from the Tech guy at RCBS after I broke two spindles. Same principle Hornady or RCBS.
