progressives are fast and produce accurate loads..competitors need progressives.
when i need lots of a single caliber, i use a dillon 550 or a square deal b., but most of my loading is 40 of this or 50 of that which is best handled by my lee classic cast turret press. with 25+ die sets in turrets stored in 13 oz coffee cans that can be swapped out in a few seconds, it's more flexible for short runs.
i won't get rid of my dillons, but my lee gets the most use by far.
ignorance is fixable, stupidity is forever...
