I think I found a most simple fix for the RCBS Rockchucker not catching primers. The slot where an auto primer feed is installed which is not used by most,will be used for this. About 4 inches or so below that slot is another slot of the same thickness. Using my table saw I cut a strip of wood about 1/2" wide and the thickness of the slot. It is long enough to be flush with the top of the upper slot and stick into the lower slot a short distance. There are already set screws there to attach the primer feed block. When you put it in place dont go to the front edge of the upper slot---it will be in way when installing shell holders. You do want the bottom end to be all the way in,or it will create an unwanted pocket for the primers to fall into. So the stick will be installed on an angle---wider at top than bottom. It seems to work as a baffle and the primers don't go into the catcher but stay on the area around it-----which beats on the floor. As Floodgate mentioned,just rake them into the tray with your finger. For those without a table saw,You could possibly use a popsicle stick--- maybe even two popsicle sticks???????? I think they would be long enough and even if they are not as thick as the slot--no problem the set scres will hold it in. Would take a little cutting,but a paint stir stick should work too. BTW,how do people get by without a table saw? I know Buckshot would mill,lathe,drill press,hose clamp and duct tape a fancier rig,but I don't think metal would give as much cushioning baffle effect. Oh--the hose clamps would be stainless steel ofcourse. I did try 6 or 8 .243 cases and it worked 100% on that small batch. *edited for Buckshop to clarify it was wood cut on table saw(about 1/2"X 5" and maybe 1/4"thick. No metal parts were cut on table saw.
