And hence why this THR category is called "Handloading" and "Reloading".
For me, reloading is mass production of lower cost than factory ammunition to work in any SAAMI spec barrel with varying degrees of consistency and resulting accuracy. But handloading is production of custom tailored ammunition specific to a particular barrel with select components and care given to produce optimal consistency and accuracy.
While my range practice and plinking rounds are loaded using the cheapest available components on progressive presses without checking the primer pockets with bullet nose profile (typically FMJ/RN) and OAL that will work in any pistol, my match grade rounds were resized separately on progressive press (which allowed for checking of primer pockets and hand priming) and progressively loaded with more consistent components at OAL optimized for the match barrel with more consistent finished OAL from less shell plate tilt/deflection.
As I posted previously, this "touch" of OCD of resizing match brass separately and hand priming could be seen by many to be OCD but I see it as necessity to produce more consistent ammunition. It is for these reasons why I still prefer to reload rifle cartridges on a single stage press.
