I began my hand loading carrier many years ago with a couple of Lee-Loaders for a couple of calibers. I only had a couple of calibers to load for then and only a little money. More time than money so the Lee-Loader was the ticket. It has other limitations besides more time. For rifle brass the case you reload can generally only be shot in the same rifle that it was originally shot in as the Lee-Loader only neck-sizes the brass.
I still have a number of these and have picked up others at yard sales and gun shows for other calibers I now have. I hadn’t used one of years, but I have them in case I need to travel light & still want to hand load.
