I sort out the badly blemished bullets as I cast, especially if the base is off at all.
Once they get past that I examine them again and sort them by weight. The heaviest ones are kept for the more accurate loads. I keep the weight within +/- 2gn (eg 173 to 177).
Gas checks installation is probably the next most important step. It MUST go on perfectly square. Various ways to do this. My method is not perfect but works for me so far. I use the Lee sizing die and run the bullet with gas check up until it just touches the die. Then I tap down from the top with a 1/4" rod to seat the gas check firmly. Then run the bullet through the sizing die to crimp the gas check on bullet.
All of this gets me down to MOA or just under. I have a ways to go to get less than that.
