We have had a similar reloading journey to many here. Had a Rock Chucker and was perfectly satisfied with it loading rifle and a limited amount of handgun (mostly revolver) ammo. That was until we were bitten by the "combat shooting" bug in 1977. We were lucky and had fallen in with a pretty good bunch of shooters some of whom had Star machines ($1000+) and a few had C&H Auto Champs. This was in the pre-Dillon days. We bought a C&H machine and, even with it's quirks, it served us well. Then Dillon came on the scene and the 550 became the standard for the average shooter wanting to load in volume; and then the 650 and the RL1000, 1050, etc.... Our old Rock Chucker has been replaced by a Redding T7 for low volume cartridges but for everything we shoot in volume we now run 3 Dillons; a 550 set up for .223 with a Hornady powder measure, a 650 with case feeder for .45ACP and 9mm, and another 550 for all the other handgun cartridges we shoot.. We shooters owe Mike Dillon and his heirs a huge debt of gratitude for putting progressive loading within reach of the average shooter. We have tested the progressives from RCBS, Hornady and lee over the years. We could live with the first two if forced to, but based on close to 40 years of use it's hard to beat the Dillon machines and the company's service. And yes, progressive loading is really pretty simple; just pay attention to the details.
