Same for me. The only press that I have ever had is my 550B. I bought it when I was waiting on a MAC10 .45ACP that was in NFA jail so that I could have plenty of ammo loaded during what turned out to be a 13 month wait. For hunting rounds I use it as a single stage. For other rounds I use it as it's intended. I did convert to micrometer powder bars and it does great with ball powder. Stick powder is very close but I'd rather measure individual loads with it.I've got a Dillon 550 that I bought from Dillon in the 80's, and it works very good. I've upgraded through the years to a "B", and now a "C". But I'm real finicky with my hunting hand loads, so I pretty much use it as a single stage, and I hand measure every powder load. I get good ES and accuracy in my loads, so speed of reloading isn't an issue. The Dillon is solid, but I strive for charges down to the tenths of a grain.
