My solution to all those tasks is to find something like deewayne2003 mentioned above, but I got a small benchtop shopfox lathe to run them in. Basically chuck it up, process a set of brass, chuck the next, and keep going. Really nice for batch operations. Also, because it's variable speed that helps with a variety of tasks on having a good amount of control.
Protip, if you went this route, I got some magnetic bars from harbor freight and mounted them above it, so all the primer/chamfer/deburr and whatever other tools are always handy.
