You will have to play with setting depth…But this is what I normally do for my 223…
That pretty much did the trick for varmint rounds. With 50 grain VMAX projectiles over 28 grains of Win 748 and an OAL of 2.265, 4 of 5 shots were touching and the fifth shot was displaced vertically by about 3/4 inch. For the group of 4 that were touching, the vertical spread was 3/16 inch. They're going squirrel shooting this weekend.
Changing seating depth didn't help a lot with the FMJs, but by the time I got around to testing those batches, a slight breeze had come up. Still, the groups were just over an inch.
