JTB,
do you have a reloading manual at all? most of them have pretty extensive introduction to reloading section on brass prep.
when i prep new brass i usually uniform the primer flash hole, because i think it helps consistent ignition of the powder. i cannot prove that and many folks do not uniform the primer flash hole.
i also chamfer the inside of the necks so that the neck doesn't shave metal off of the bullets when you seat them.
i usually also run then through the sizing die as well.
if you can shoot well enough to tell the difference between new brass and once fired brass, you're a heck of a lot better shot than i am.
do keep track of the number of firings on the brass and when the whole lot is at 4 you might consider neck annealing.
do keep an eye on your brass as to it's lengthening and if it lengthens too much, be sure to trim it back. for best accuracy, due to consistent neck tension, if you have to trim a few pieces, you might as well trim the whole lot back to the same length.
in a bolt gun, you can adjust the FL sizing die to just bump the shoulder a minimal amount to reduce the amount of sizing going on. but then that brass will "fit" that bolt gun only, in general. if you are using a semi auto you'll have to size the cases enough so that they chamber easily.
