[QUOTE="del2les, post: 1953162, member: 9299"] Under normal circumstances and pressures, enlarging the flash hole will result in increased back pressure into the primer pocket with the resulting increased expansion of the primer, flattening, and expanding the primer pocket much quicker resulting in ruined brass. The only times I have ever found it necessary to enlarge a flash hole is when loading and using revolver squib wax, plastic or rubber bullets for indoor gallery shooting. These handgun loads are powered solely by the primer pressure, and a normal flash hole without the powder charge pressure to reset the primer may cause the primer to back out and increase drag or lock the cylinder. These case heads are marked by using a colored Sharpie or light spray paint and are NEVER to be used for regular loads. [/QUOTE]
