Had set up a Dillon 1050 with the Mark 7 system, specifically to put primers in 300AAC cases. Once I ran 400-500 pieces, I turned the machine over to a fellow after another 400-500 pieces primed. I no sooner than left the building and the operator had a sympathetic detonation of a full primer tube. Luckily, the machine had the Plexiglas safety shield in place. Primers were embedded in the wooded table and the low primer indicator was launched HARD to the top of the 20 foot ceiling. They said it sounded like a 12 gauge and it got everyone’s attention. Luckily, nobody was injured.

The APS hand tool goes from good to great when the return spring is exchanged for a much weaker one, thus allowing the user to really feel the seating process (contact followed by crush). The feel of the modified tool is nearly as good as Sinclair’s tool (the gold standard IMHO) which requires feeding the primers one at a time. My Sinclair tool goes unused these days as the APS tool is so much faster,
