I've used them for years on and off. I too began loading loading for 22 Hornet on one and still do. I just don't load enough Hornet to buy dies. As for the 38/357, I have a set of loaders for each caliber but don't know if each can be can be used for the other. For rifle calibers I use Imperial Sizing Die Wax to make resizing easier but have had good results using Lee Loaders. Give it a try and report back.
