I'll differ from the others in that I prefer Alox tumble lubing and the Lee sizing method to either tedious pan lubing, or lubrisizing.
For those who lubrisize but have used Lee's tumble lube process in the past: why did you switch to lubrisizing? I'd concede that it's messier to tumble lube, but it certainly doesn't seem slower to me. Lubrisizing is definitely much more expensive, with lubrisizers running $100-150 at least,and top punches running about the same price as the Lee sizing dies that handle all bullets of the same diameter. It seems a lot of kit to accomplish two fairly simple tasks. I use alox tumble lube applied even with 30/30s at 2200fps, and have no leading, and my lee dies seem to size pretty accurately.
