I have the Lee Classic Turret. It makes 9mm and .45 ACP much faster than a single stage. I used to make 100 9mm in about 2 hours on a single stage. Now, I make 100 9mm in 40 minutes.
Making rifle rounds isn't so fast, because of case prep. But, once all case prep is done, I can make 100 .223 in 35 minutes.
