Got a Dillon SDB from a friend a couple weeks ago. He upgraded to a 650 a few years back, and this one was collecting dust, so we made a deal.
Ms. Dillon as I call her has given me quite an education in two weeks.
She demands your undivided attention, she is unforgiving of any lapses, has a healthy appetite for small shiny things (cases, primers, and boolits) but once you learn her quirks, she's capable of making a pile of ammo in a hurry.
This is my first progressive press, and my first Dillon, and now I see why everyone speaks so highly of them. What an ammo factory!
In two weeks I've made almost 2K rounds of 9mm, 40, 45 ACP, and 38 Special, and man what a machine!
In short, I can say I am now hooked on Dillons. They are worth every penny.
