    Donuts in 243 necks

    Guys (and girls). I'm finding excessive seating resistance in my 243 brass. It's all Norma and was given to me with unknown history. It should mostly be once fired. I thought it maybe be just a bit old so I annealed it all which improved things but 85g HPBTs are soft jackets and show seater marks at the slightest resistance. On further inspection it looks like the neck-shoulder junction has the good old donut.
    I'm sizing with a Redding Type-S FL die so the brass gets a light working over each time.
    I have a Forster trimmer but nothing has yet to measure oversize and require a trim. I was thinking I can buy the internal reamer for it. Anyone used this setup successfully? Or am I just too mean and I should retire the logo the scap bin?
    The range of what we think and do is limited by what we fail to notice. And because we fail to notice that we fail to notice, there is little we can do to change; until we notice how failing to notice shapes our thoughts and deeds
