weigh your brass and skim turn your necks, uniform the primer pockets and debur the flash holes.........then sit at the table and........
measure your bullets for OAL length and sort them into groups separated by 5 thou differences......no take those groups and sort them by base to ogive length in 5 thou differences.....and then take those sub groups and weight sort them......after sorting 1000 berger bullets you'll have one big group of 300 bullets for the big matches, 200 bullets for the small matches, and a whole bunch of practice batches and fouler bullets
If you can't get a particular bullet to shoot for you, try another lot number....I have berger bullets from 2 lots that are 40 thou different in overall length one lot number shoots split groups at every distance, the other lot number shoots round holes....my barrel prefers the shorter of the 2
