I find it hard to believe that someone can think that a progresive press that weights less than the handle on my Dillon is better than my Dillon.
Skinny, If your going to load extreemly large amounts of 1 or 2 different round get the 650 Dillon. If your going to load for alot of different round go with the 550. I`ve been useing a 550 since the early 1980`s. I do only load ball powder, because they meter so much better, but have loaded for several rifles that consistantly shoot under 1/2 moa with the ammo loaded on my Dillon. I do agree with Billy on 1 thing,
( I also found out through my own ignorance you can produce a lot of really crummy ammo in a hurry if you don't pay attention to details and follow destructions. )
