Yes the Lee Loaders work, but I imagine it would be pretty tedious doing larger amounts of pistol ammo. I have several for rifle, and I like them for neck sizing, and I suppose theyre ok for the guy that reloads 20-100 rounds of say .308 a year.
For something small I would still recommend a bench mounted press and just stick it on a board and clamp that to a table when you need it.
Also there are two other tools that are used by hand that come to mind, the Lyman/Ideal 310 (uses special dies) and the Lee Hand Press (uses standard dies). These work well, but I find it is much easier to have your press mounted on a bench so you don't have to set it down when you need an extra free hand.
