Have had a Dillon 550b for nearly 20 years. If you don`t mind spending more for a Dillon, whats not to like?
-built like a tank, unlike the Lee. No constant fiddling for adjustments. Cheap plastic parts that seem to always break at the worst time.
-very easy to switch calibers/primers.
-can buy a case feeder for the 550b (works perfectly for me).
-among the best service/warranty that I have seen.
-all my powder measures are so consistently accurate, it`s almost spooky.
- you can reload for about 160 calibers. Yes, no one will need that kind flexibility, but it`s resale value is fantastic. I have been going to shows around Southern Ontario for over 25 years, and only 3-4 times have I seen a Dillon for sale. And they end up selling within the first hour. But I always see Hornadys, RCBS and lots of Lees` presses for sale, and they rarely sell.
Manual indexing? This is a plus. It`s like having a progressive AND a single stage reloader.
So, if you can, save up the extra money and buy Dillon. If not, I suggest the Hornady....
