Both, and then some.
Constantly varying 'what and how much' gets done 'when',,,
I have a small bench with (1) Inline press mount. (Quick Attach version)
A lot of my priming may depend on which press (LNL-AP or RockChucker***) is in the mount, what caliber it was used for last, and how many rounds am I working with.
*** My RockChucker was part of a kit that included the hand primer. I added a new caliber to the fleet recently, and could only find a Hornady shell holder that day. (RCBS Hand Primer doesn't work w/Hornady shell holders)
Anywho, I remembered the 'Chucker came with the little 'prime on the press' primer arm,,,, Never used it before,,,
Dug it out of the closet,,, Set it up,,,,
Placing those little primers on the pin requires both patience and a very steady hand,,, I found out quite quickly I have neither!!!!
