Re: RCBS Pro-2000 Press Info
I will check the spent primer tube fit, as a matter of fact I was told by RCBS that spent primers are the main culprit with the APS jamming. I am sure you are correct that it is another potential trouble spot. If you have some spare time I would suggest that you take both plastic top plates off your press so that you can see how they go together. It is fairly straight-forward and should definitely be included in the instruction manual - but isn't. By top plates I don't mean the portion with the shell holders that indexes, go for the plate under it with a half-moon shape and also the top plate of the APS system - each is held in place by three capscrews. Fortunately there isn't any small parts or springs to fly off and the two plates go back in place easily. I am going to check under the APS plate regularly as a surprising amount of powder had accumulated under it, as well as the live primer - could have made a small fire if the primer had let go.
I had powder going everywhere when I set the press up, a bunch got into the APS system but you cannot see it or check for it without removing the top plate.
