I have both the Hornady LNL progressive and a Dillon 650.
I have loaded more on the Hornady as I have had it longer.
Both are good machines and work well. Also both have their little quirks that keep them from perfection.
If you had said you were only loading pistol I would not hesitate to recommend you go Dillon instead.
For rifle mainly and some pistol the Hornady is good too but I think I like the Dillon for loading pistol more than the Hornady.
I give Hornady an advantage on the powder thrower and sizing the larger cases.
I have case feeders on both and they both seem to work fine as well.
Hornady Customer service is excellent but so is Dillon.
"Anyone taking up handloading necessarily plays with unknown factors and takes chances. But so does anyone who drives a car,goes to a cocktail party,eats in a restaurant,or gets married."
