I have used a Pacific 366 and now Hornady 366 since 1981. Hornady helped me rebuild the Pacific. Over 200,000 reloads based on my powder, shoot primer, wads purchased. I keep good, records. I had a Mec in the late seventies.Good press but I like the Pacific better. To each their own. If you load good quality shells it doesn't to matter what press you use. Be safe and shoot as much as you can. I couldn't to afford to replace my press at today's costs.
