If they are for LR use, past say, 600yds or so, the 220SMKs I prefer for this application usually get sorted for bearing surface length, then base to ogive, then meplat uniformed. Meplat uniformed bullets from the tool I use are uniform in length to somewhere around .0002 or so. Base to ogive sorted bullets do seem to have more consistant BCs than non sorted bullets, but most of the variation in a lot of bullets in in the meplat. I sort BS length to reduce ES primarily, but some have argued that both BS and base to ogive measurements are equally prone to cause BC variation.
