A few days ago I decided to get some Hornady Amax 178 grain projectiles in .308 Win. I loaded them up according to the Lyman manual and noted that the COAL according to Lyman is 2.780. I noticed this to be true also of the all the bullets greater than 175 grains, except the Sierra 180...it called for the standard 2.800 COAL.
So why do the longer bullets require a shorter COAL? I am sure I could load them at the standard of 2.800, but they grouped pretty well as is.
