The best compact and portable press available is the HDS Compac Tool.
You can bang out a handful of cartridges a night on the old Lee Loaders, but they aren’t for volume loading and are slow, slow and did I say slow?
The Lee Hand Press is decent, as I said I have two.
They can be a little awkward depending on what cartridge/bullet combination you are using.
The old 310 tools do not full length size so they are fine for straight wall cases but most bottleneck cases will eventually need to be full length sized in standard dies or they will no longer fit in the chamber.
