I didn't know this was a "find the typo" competition ;-) I remember finding a few, as well as a couple times when I thought I drew a conclusion from the data that you didn't mention... as I re-read I'll post up.
I was very pleased with the book. Cal's barrel test was great, although those tubes are out of my price range. The dispersion article was great in that I finally have something to point people to when that old saw gets trotted out. I have been doing quite a bit with aiming points, myself, and would really like to see work on that. I've been drawing them up in Visio with some to-scale crosshairs, trying to get very accurate aiming points for the rather fat (0.06mRad) crosshairs in my tactical-style scope. It really does make a difference, especially at longer range.
The reloading information and .22 data were the real meat for me - although certain areas could be fleshed out more with additional live fire time (a precious resource, for sure), they provided a great starting point for the precision reloader who hears on this forum (and benchrest.com) that you MUST weight-sort brass, trim and point your bullets, anneal every firing, etc. Having the gains laid out for certain situations allows one to focus their efforts on the best returns for their time and money. The fact that multiple calibers were used in all the tests adds additional usefulness.
I agree with your final assessment of the .22 ammo test - it's hardly conclusive, but the compiled data is very useful. I'm actually in the process of building a long-range 22LR setup, and it's hard to find good data. While excellent short-range precision is a well-documented pursuit, absolute mechanical precision isn't that important when lobbing 40gr pills to 300yd at 1050fps. A good BC and consistency are more important - I photocopied the charts out of that section and used them to fill my shopping cart with .22LR ammo to test in my new gun, selecting high, consistent BCs with reasonable SD numbers.
Finally, just having the BC of the bullets was great! I pulled a bullet from my CCI SV ammo and measured it (0.500") and plugged that into my app along with my measured velocity and your BC numbers. I was easily able to go 10 for 10 on a 12" plate at 300 yards with that data, using a plain-jane 10/22 that's only good for 2MOA at 50yd! (It was dead-calm out.) It really is a lot like taking a .308 out to 1000yds, as evidenced by spinning almost 3 complete revolutions of my turret to handle the 155" of drop to 300yd.
One question on the .22 data... what are the grayed-out boxes for? I couldn't find an explanation in the text, but maybe I just missed it. I got that the bold were higher-than average BCs, but most of the gray were just a few types of match ammo without any easy to discern pattern.
