Just guessing, but it really sounds like the famous "crud ring" formed when firing 777 with a very hot primer...

I do you use bore butter but not between shots, and not with sabots they have their own lubrication system. A lot of people are going to tell not to use BB at all but it works very effectivley at reducing fouling, including plastic fowling if it is used properly. I would add that no BB is better than a lot.

Barrel seasoning into todays metals really isn't probably the best term to use, although that is what BB says. I use the term I "treat" the barrel with BB and I do it with a very hot cleaned barrel, heck I am even treating my shotgun chokes the same way now reducing the plastic fowling they take on dramatically. I beleive that is the true value of BB reducing fouling - and as a side note I would include reducing the "crud ring" - I do not get it at all.

If you would like further dialog on how this individual treats barrels let me know and I will send you or post copy of my routine.

Good luck... and I am sure you will get a lot of hot opinions...
