IF - that's a big if. Pistol powder is usually non bulky Bullseye or Unique to make good shooting economical loads.If you use a powder that is bulky enough it will overflow the case and warn you of a double charge. Of course this will not work with Unique or Bullseye.
+1 Only instances I am aware of double charged and no charged rounds have been with folks who use progressive loaders. Speed in reloading has never been my objective..That type of wreck is what I usually picture when somebody posts they just got a new progressive reloader. No charge and double charge rounds can make a shooting situation interesting. Not for me but for them. Of course they usually have a POS gun like a Llama or a Taurus rather than a nice Colt or S&W, but sometimes you see the good uns destroyed. I would like to harvest the parts on that one.
When I blew up my anaconda I could pull the trigger and what was left of the cylinder would turn and the action would go all the way through.Hey do you think the timing is off? 😏
Actually, the only time I have screwed up in over 36 years of reloading was with a single stage press (brain fart = no powder). I have loaded many times more rounds on my Dillon 550RL without incident. Granted, I'm a more mature reloader now and visually check each case.+1 Only instances I am aware of double charged and no charged rounds have been with folks who use progressive loaders.
