I have been reloading and shooting for 8 months now. I am quite particular. I am loading for a 300 ultra mag rite now and will be reloading for a 6br next week. My question is on the primer pockets for the ultra mag, I use a Haden's primer pocket uniformer which works very well, but I have been using the uniformer to clean out the charcoal residue in the pockets in-between shooting each case. Is this necessary? Thanks
