There is another issue that should be accounted for with necks so clean; bullet galling.
Carbon works just fine to separate the copper in your brass from your bullet jackets.
I coat bullets anyway, and many lube necks, but neither is needed -unless you ultrasonically clean the necks.
The fella that doesn't clean his brass at all is probably miles ahead of us.
I pretty much agree. Especially with the ultrasonic-cleaned necks. Bullet friction/tension with the US cleaned case necks was much different. I noted this so much right off the bat while seating bullets that the first thing I did at the range was compare the US cleaned reloads (with the squeaky clean case necks) POIs to identical reloads with cases that were carbon-fouled (no US cleaned). You guessed it. There was a 1 1/2" to 2" difference in the POIs at 295 yds.
As a consequence, on the cases that I've already US cleaned, I now lube the case necks with Imperial Resizing Wax and then remove as much of the Was as possible with dry Q-Tip ear cleaners prior to seating the bullets. This still leaves a light coating of the Imperial Case Lube in the case necks, and the resistance to bullet seating is pretty similar to my carbon-fouled cases. The POI and MV is now the same with these US-cleaned cases, as with the carbon-fouled ones.
Good points that you've made. My experiences with US cleaning lead me to very similar conclusions. I never did anything to formally clean my cases for decades - such as vibratory or tumble cleaning them. Like you say, now that I've US cleaned some brass, it seems like not cleaning them served me very well - maybe even put me ahead in this game/hobby.
