    I often uniform primer pockets with a Lyman uniformer, then ream/deburr the flash hole with the RCBS flash hole tool.

    I also uniform primer pockets and de-burr the inside the case flash hole with a Lyman tool after I size and trim the cases.

    If you can use Lapua brass, you can get away without doing any of this. However, if you have to use Win. Rem, etc than your going to have to uniform and clean primer pockets and flash holes.

    I used to use a Lyman tool, but it indexed off the case mouth and I normally deburred the flash hole prior to shooting (so I didn't want to trim to a specific length until the shoulder was completely formed and consistent for my rifle.

    So, I changed to the Sinclair tool, which indexes off the inside of the case (web area around the flash hole).

    K&M Services also sells a flash hole deburring tool that indexes off the inside of the case rather than the case neck, and is the brand I use to inside deburr the flash holes.

    Thanks for all the input. The cases are Norma brass for 300 WSM that I bought new and have fired once, have cleaned and neck sized.

    I have fantasies about flash holes. Unfortunately, Norma flash holes are drilled, and there is nothing to deburr.

    They may be drilled, but there are still burrs. I just looked in a box of Norma 300WSM and many of them have burrs that are visible. Once they are deburred, there is just a small bevel all around the hole (nice and even).

    "If you can use Lapua brass, you can get away without doing any of this."

    True enough. But, at those prices, it should be flawless and it isn't. I'll just take my time, work over conventional brass and get by for much less expense. I don't reload because I'm in a raging hurry anyway! :)
