Just like you, I started with a .38/.357 Lee Loader 46 years ago, loading .357 Mag for a Ruger Blackhawk. Despite the furious pounding necessary to beat brass into the Lee Loader, it only neck sizes cases. To my dismay, my Ruger had inconsistent chamber diameters. I ended up pounding reloaded cartridges in and out of the cylinder. Not good. I would detonate two or three primers per 50 round batch while seating primers. Not good at all. There is a very good reason Lee doesn't make them any more. I gave mine away. All that said, if one were in the backwoods on a subsistence existence, the Lee Loader would keep one in limited purpose ammo.
