I chose Dillon on the recommendation of my LGS owner. I started reloading pistol and decided to buy a SDB. Later I purchased a .30-30 rifle. Wanting to load for everything I shoot. I traded in the SDB on a 550B. I noticed my LGS still had my trade in. I thought it would be nice to have one set up for large primers and one for small. So I bought the SDB again. I am a "happy-camper" now.
