that's just it, SPP, or LPP, they both work...anyone that reloads, just has to inspect each case, either before cleaning, or at least when inserting into the press's shell plate, if an automatic case feeder is not in use.
i always check the case bottom before inserting into the shell plate, so that slows me down, but then too, i even check each case for powder drop as well...which is also slowing me down, but then too, i am in NO rush to reload ammo....
time spent checking each process is time well spent, to avoid a possible catastrophic event.
i'll let the factories push out thousands of rounds per hour.
