Well, we'll see how it all turns out.
 
TAC is a big help. I have a factory Remington 700 .223 that I started out (several years ago) with 6-8 rounds of bullets imbedded with fine bore-lapping grit. Since then it has been shot several times for at least 500 rounds with no cleaning, using conventional bullets and TAC. After 500 rounds there is only a faint bit of powder fouling, and virtually no copper fouling. Is is the powder? I have had excellent luck with TAC in the .204 as well, with factory barrels that didn't get any special treatment.
 
The one thing I am becoming convinced of is that so-called break-in doesn't need to be done on any barrel anymore. There are quicker ways to get to the same goal-line.

double based flaked powders have always been marketed to burn cleaner, and after shooting a ton (literally) of them --I think they do. The fact that shooters get results by doing it and some shooters get good results by not doing- such a wide range of responses in between implies the break ins lack of specific importance. Sometimes a wonder if the breakin is more of the shooters perception that after this point the gun should be shooting its best groups. -- then decisions about load work up, bedding changes, trade the gun off come up. I certainly agree that the consideration for break in on a hunting gun is a waste of barrel life.

TAC has a small amount of bismuth in it, ,which supposedly cuts down on copper fouling. It seems to work, based on rifles I have shot it in compared with the results with some other powders.

The sequence you suggest with "break-in" is pretty much spot-on, I would say. Back when I started shooting many people suggested that a centerfire barrel was broken-in after 200 rounds or so. At that time the advice was to clean them every 20 rounds (I don't know why), which means that after 200 rounds the barrel would have been cleaned 10 times--the same number of cleanings usually advised in the initial sequence one-shot-clean method. My suspicion (based on my log books) is that if we shoot them for a while they get broken in--whatever that means.

I still love to hand Lapp all my barrels when I first get them. You learn so much about the rifle when you lap it and fully take it completely apart for a good cleaning. Most people would be surprised at how simple some rifles are and how many tiny parts they depend on during a hunt that they will probably never ever see. I am going to give the Ultra Bore Coat a try on a shot out barrel and see if it makes improvement or stays the same. I would try on a new barrel but what fun would that be. LOL!!!
