my arm didn't get any bigger but I got a sore shoulder and can feel it in my hands.
the roller handle for the dillons is a brilliant invention, if I ever see one for the P/W's i'll get three of them.
they compare to the shovel handle for the star sizers.
I have had an occasional issue with the Dillon primer tube fillers but it almost always centers around adjusting the little plastic drop through adaptor up or down just an 1/8th or 1/4 turn on the screw.
I bought the second one because I hated dialing in the thing when switching from big to little primers.
now I just have them set and leave them alone.
I still have to poke the wolf SR primers but have done that so many times I usually dump 2 boxes in the big flip tray and use both hands to fill 2 tubes at a time so it goes pretty quickly.
and no I don't really care if I get 105 in one tube and 95 in the other I rarely run off 50 or 100 count batches of anything except test ammo for a new rifle.
