I have an old RCBS single stage , which I've owned since age 18...
Works good !
My buddy has a Dillon.
I can load as fast with my old RCBS as he can with his Dillon, and, I can make better ammo.
As I load, ..he tinkers, ..adjusts, re fills, ..changes settings, etc.
.
I always sort of wanted a progressive, but, As years pass;
I am actually pretty darned happy that I never owned one.
.
If I were to go progressive, I would get a simple turret press, with an indexing head, like the "LEE," and be done with it.
