I load 40,000 plus rounds of pistol amo yearly on a 650. It does require some maintenance with that many rounds and the primer feed can be a frustration on occasion. It is fast.
I also have a Hornady auto with the lock-n-load die system for loading smaller quantities of amo I don't use as much of. It is much cheaper and in most cases quicker to change calibers on than the Dillon. It is a big open press and fairly easy to work on when things need adjusting or go wrong.
It would not be an easy choice choosing one over the other. Dillon really does have a no BS warranty and I have used it several times and no charge.
