What really speeds up the loading process on a Pro 1000 is the case feeder, it limits what your left hand does to placing the bullet in the case and your right works the lever.
So it's place a bullet, pull the lever down/push it up-repeat for the Pro 1000.
As I see it, for the Breech Lock Pro it's place a bullet(not sure which hand, it' way in the back), pull the lever down, load a primer via the pez dispenser(left hand), load one case into the hole in the die plate(right hand?), push the lever up and seat the primer - repeat.
That's 3 operator inputs at 2 different points in a single cycle and would be an opportunity for me to forget the primer and have powder leaking out, just me though.
I've watched a lot of youtube vids on the Breech Lock Pro where loaders forgot to work the pez dispenser, that's what soured me on that press.
