[QUOTE="jlanecr500, post: 4422684, member: 16430"] The SAMMI standard flash hole is .080" You can use a #2 center drill which has a .078" pilot on the end to keep it centered in the flash hole. Use it in a drill or simply hold in a vise or with vise grips, insert it into the flash hole and rotate the case with your fingers. The following link is for a 6" long #2 center drill...Perfect for the job. With a slightly chamfered hole, the primer flame is allowed to propagate into the powder column evenly at a 60 degree angle 360 degrees around the flash hole. Burrs can cause flame propagation to be uneven or even one-sided.
