Michael, you bring it right back to the difference between shooting UNTIL hitting, and shooting TO hit. The is not a BR or Varmint for score shooting site.
We're hunters, so the FIRST shot counts.
I wouldn't shoot a bare bullet out a bare steel barrel anymore than you. I don't know that anyone has suggested it.
Now I can't provide a link or anything, but I've read somewhere a carefully performed test, that clearly demonstrated the tenacity of oils to burn back out of a bore. I don't remember, it may have been in a Precision Shooter, or Varmint Hunters issue..
I know that before I went to dry pre-fouling, my first shot was always off. Perhaps from velocity/pressure anomolies like you see. Then I could shoot a group which I'd later throw out as unsettled in fouling.
This was normal and left me having to setup and shoot my gun before hunting(not always easy without a range).
I carefully watched moly shooters work out a system over the years to get around the 20+ rounds to settle problem. Then I did a buttload of testing with tungsten instead of moly, with a focus on fouling and cleaning requirements.
Let me tell ya, tungsten, as a bullet coating and pre-fouler is a no-brainer solution to a handful of common issues.
It works, and I have yet to hear of a single issue with it.
So I've laid out a alternative to leaving Sweets(or another cleaner) in a bore. And I'll go as far to say that with the right tools you can clean a bore after every firing without hurting anything at all. If anything this might reduce carbon constriction(the final killer of all barrels), and greatly extend life.
