I have a Lee 1000 that I've used for my handgun (9mm, .40S&W, & 10mm) loads and for that, it works very well..
My .204s and .223s, don't work well in the progressive and I stick to my single stage for those. For the problems encountered in the progressive process with the 1000, it is much faster for me to use the single stage and I get more precise loads.
