Heres a short video of a star sizer in use. I think its hard to beat this set up. Take the as cast bullet, place it in the die nose down, pull handle, bullet drops into box ready for loading. Depending on what lube you use they come out looking like factory purchased bullets. Clean, shiny with nice full lube band. You can also use harder lubes for rifle load or softer, its up to you. Also it seems to be an advantage that you can cast, size and load all in one day. Yes I know some people like age the casting...
To me, just one mans opinion, it just easier and yields a good result. Whats not to like?
