It depends
When I load my for my rifles (except 223 AR blasting ammo) it is a labor of love. Tumble, size and deprime, clean pockets, trim, tumble, prime by hand, weigh each load, seat bullet, crimp, reinspect, in the box. I do no more than 50 at a time. During load development, I will start at min powder weight and work up in .3gr increments in 5 each. Ill then head to the range. If Ive loaded up 50, that gives me a 3gr spread. Ill usually find a sweet spot somewhere and then go back to the drawing board to go in .1gr increments. Ill again go through the process and clean primer pockets again.
Auto brass, not so much. Tumble and load.
