A set of dies in that caliber, a press (preferably progressive, though there's nothing wrong with single-stage.), an accurate scale with check-weights, a good reloading manual (from the better bullet companies and powder companies), a case mouth chamfer tool, case lube, an inertial bullet puller, and a bench.
A set of veneer calipers turns out to be almost indispensible, too.
Then you need primers, bullets, powder, and boxer (read: non-Berdan)-primed cases.
And finally, you'll need to hang out at The Firing Line's own Handloading and Reloading Forum, which is where I'm moving this thread to.
Good luck!
Folks, what have I missed that he
needs? (and yes, I think EVERY reloader needs an inertial bullet puller!
)
