Like the article says though, they are no replacement for your D type press. When resizing and de-priming, you must unload the primers caught in the chamber below the shell hold, ever 20 cases. That is for large Rifle primers.

I have had numerous issues though with the quick change bushing. It can move around on you and cause seating depths to be inconsistent. If should bumping there can also be up to .005 of movement in the die. Imagine my frustration when trying to resize brass and bumping shoulders by .002 when there is a variance of .005. I have found that turning the bushing so that it does not aline with the stop button helps solve this. Though it does introduce some concentricity issues.

The included priming kit is one that has to be used by the feel method and is surprising quite responsive. I can feel the bottom of my primer pockets almost as exactly with this tool as I can any hand held primer and much better then I can with any D type press priming system. You can also use a the RCBS ram priming die in circa with this to seat via the solid stop on the press. Something I have experimented with but now believe that the feel method is better. One perk it does have is that unlike the Sinclair tool that adjust prime depth in rather course increments of .002 the RCBS ram primer in conjunction with the lee press here can adjust primer depth in much finer increments.
