Well, of course you need to adjust seating depth, that is just one of the major critical components, some argue the most, to get the best accuracy. Also, measuring COAL is worthless to me, unless your COAL is a bullet seated in the lands of the barrel and your starting point. Otherwise, it means nothing regarding the the throat of your barrel and the seating depth of your bullets.
I have 3 barrels with 3 different COAL measuresments to the lands. However, I also don't measure COAL, from case base to bullet tip. I measure Case Base to Ogive using a hornady tool.
OK, on another note. Shootingmathews- if you have not done this it might be time you try it. Measure all your cases and sort by 1 grain differences. For example I sorted my brass from 194 to 195 grains and 193 to 194 for this last batch of nosler brass. I keep them separated. This is all done after trimming etc, no primers. Then sort your bullets by .1 grains. In my last batch of Bergers they went from 139.8 to 140. A few are 139.8 and I use them to get on paper or test pressure. For groups I shoot the same weight brass and bullets. Just a thought. If you want to get to the next level measure bearing surface of each lot of bullets. I had a lot once that had .030 difference in a box of 100. That is horrible quality control. It was a box of target bullets so I didn't care really but the difference in bullet performance is surprising with that much bearing surface difference.
