I upgraded my DPS2 today, very easy to do!! I loaded up some 30-30 ammo with BL-C2, filling took about half the time it took before, maybe even less, it would be done filling before I could finish seating the bullet in the last case charged.
Clean up was much easier, most of the powder flowed out on it's own, didn't take much brushing to remove the what was left in the nooks and crannys!! Just ran it to empty the delivery tube and I was done.
It comes with a bushing to insert in the end of the delivery tube for some stick powders that may tend to overfill.
The only issue I had is the little door on the powder box that you tip down, is kinda stiff to open compared to the original, other than that, no problems.
