i tend to agree with that. For PRS style shooting, if i knew i was only going to be practicing speed barricades on 2-3 MOA targets, i might make some 'practice ammo' but the only difference in that and my 'match ammo' would be that i would just throw the charges instead of weighing them. brass prep would be the same. (anneal, resize, trim, but never uniforming primer pockets or flash holes)

but in reality, i never do that because i usually like to change up the speed in my practice and run barricade then take a shot at a 1/2 moa target or hostage flapper
(not that i have had any time to practice this year...)
