It's up to the op what he buys.
Given the number of rounds a hill stalker/keeper will use in a year, a Lee set up will be more accurate and cheaper than standard factory with a bit of bullet/powder/length tweaking, but it takes time to build up an accurate load, and costs money for the consumables, so initial costs need to be offset.
X, Y, or Z dies and presses can produce more accurate rounds, you can play about with primer pocket uniforming, flash hole de-burring, neck sizing, annealing, etc, but shooting into a Minute of Fox, or Minute of Deer with the chamberings that he proposes, at the ranges he is likely to use them at, shouldn't need that degree of buggering about.
