BS
It is hard to get a double charge on a progressive in the first place. When you pump the handle the case/die moves onto the next stage making it really hard to double charge a case.
That and using a single stage to reload any volume of pistol ammo is a daunting task that is sure to turn a noob off of reloading real quick.
550 is not a auto indexing press like the 650 so you have to turn it your self
