As a jeweler you already know equipment makes a difference. Be positive your two Weatherby mag cases will fit in whatever you buy.
Look for a Forster co-axial press. My BIL has owned just one press since the early 1980's and he is a stickler about accuracy. LinK:

Yes, expensive and a standard RCBS press can do the same, almost. Link:

You will need a Bench. Personal preferences here. Long. deeper than a normal countertop. Case lube, cleaning lube, cleaning liquids, and sandpaper-like carbon particles will come in regular contact so the surface needs to be tough or easily replaceable and cannot be metal. It needs to be well-constructed-many lag bolt the legs to 2x4 studs in your home. Have a foot rest that will allow for heavy containers to help keep the desk steady.
Remember-keep smokeless powder, primers, and black powder in separate storage locations. Never have two powder cannisters open on your bench.
You will need good lighting. If you use a digital scale it may need to be on separate line from fluorescent lighting and sheltered from a/c ducting.
You will be measuring a lot-get a dial or digital caliper that is accurate and easy in your hands.
Create a separate favorites folder for the component websites you will visit. Because of the shortages check your local garage/estate sales in addition to the various retail sites.
Yes, I like RCBS dies. I like the RCBS autoprime. I have an RCBS 10-10 beam since 1985. I have a Lyman case trimmer w/10 collets, a turbo tumbler, and a bunch of hand tools. I have a Frankford stainless steel wet tumbler.
Nosler makes very good bullets.
Handloading is a great hobby. keeps you sober, off the street, and very rewarding.
