I had no experience reloading what's so ever. I kept visiting here and it seems the majority here had 650s. After a lot of reading and watching the utube videos, plus the lifetime warranty I went with the 650. I got it, watched their video many times, had a few newbie questions answered here I finally got it. I'm still slow, only a couple hundred an hour but I still stop and weigh and measure every 15 min. Or so. I'm comfortable now and when I get back to it I'm sure I'll be cranking them out quicker. It's fun to go to the range using the micromotomer, seeing the difference from factory rounds compaired to reloads. The reloads are much closer in feet per sec.
