You're trying to use logic here. Stop it before you really hurt yourself.
The ITAR documents are substantial and like most legal documents, require a lot of reading and then some interpretation at the end of the day. Then you have fact that the export of firearms, ammo and parts falls under two different US Departments: the US Dept of State regulates the export of handguns and rifles and tactical shotguns, and military scopes and ammunition and ammo components (and a whole pile of other things). The US Dept of Commerce regulates the export of sporting shotguns, and shotgun ammo and components, and sights/rings/mounts and non-military scopes.
Neither the US DoC nor the DoS have a list of OK stuff and not-OK stuff. This is because everything that is controlled under ITAR for export, also needs the manufacturer thereof to keep their paperwork current. One manufacturer's rifle stock might be OK to export (with all the export paperwork in order of course) because they have their manufacturing paperwork in order, while another manufacturer may have a very similar stock but if they have not bothered to even file the paperwork, their products can never be exported, even with all the other export paperwork in order.
Reloading tools are not regulated for export under ITAR. Automated reloading tools are regulated because they are considered commercial manufacturing equipment. I believe the automated equipment is specifically listed in the ITAR so it is definitely regulated for export but hobby equipment (you'r average Lee or Dillon or RCBS press and all the add ons) are not mentioned at all so they are not restricted for export.
You can bring back cleaning supplies, cleaning tools, wrenches and screwdrivers, etc. You can bring back reloading presses, dies, tool heads, parts, etc. as long as you don't have any actual components included (no bullets, no powder, no primers, no brass) because those things are specifically listed in the ITAR regs.
If you ever want a specific answer regarding does something really needs or does not need export paperwork, you have to identify the specific item, by manufacturer and SKU/Part Number, and then call the US DoS and DoC to get an answer from the horses mouth (or perhaps the other end of the beast). You'll probably need to ask for an answer in writing (good luck) if you have doubts and be prepared to educate the US agents at the border (if you're ever stopped) because they probably don't know the law either.
Best of luck.
