I've used these for years. I use standard primers.
The simple way to load these is to make a fairly stout rectangular wooden frame sized (length & width) so that you can just fit a block of paraffin into it . If you shoot 38 Special, a block that has 50 through holes can be made the same length & width as the block of wax. Also make a relatively heavy "press block".
To use, place a block of softened paraffin into the bottom of the frame. Place the block containing the 50 (unprimed) cases into the frame with the case mouths resting on the wax. Place the press block into the frame, its bottom resting on the case heads. Place the frame in a small arbor press, pull the handle far enough so that the cases go just through the wax. Seat the wax wads to the bottom of the cases with a (T handled) dowell turned just fit into an empty case. Clean the cases up & prime. Takes longer to read about than to do.
Note: If you decide to use the cases for regular ammunition all wax residue must be removed. Not just mechanically (tumbling), but chemically (degreased). Otherwise, squib loads are very likely.
Be careful in using these. The primers drive these harder than you might imagine.
