Hi...
I run two Hornady LNLs, one set up for small primer and one for large primer. My son runs them at about 400 rounds per hour without the bullet and case feeders. Took the automated case and bullet feeders off the presses...too noisy to use. Mostly load semi auto pistol and .357Magnum on the LNLs.
I bought two Dillon 550s but decided I didn't really need them so I sold them.
We also both use Rock Chuckers for smaller batches and load development. I am retired so I load big bore revolver cartridges on my Rick Chucker usually in batches of between 2-300 at a time.
