"Sometimes when we barrel a rifle we create some tiny smears or burrs where the chambering reamer shears off the lands along the slope of the leade, I have some thoughts about WHY this happens, and how to prevent it, and even how to get rid of it mechanically, but I digress. It DOES happen. And when it happens a copper shine can occur in the first and last 2-4 inches of the barrel, but not in the middle. And I believe that most of the time you can "fix" this coppering phenomenon by shooting/cleaning/shooting/cleaning/shooting 3 to 5 to even 10-15 rounds and IF IT QUITS COPPERING......... it's fixed."

The above was posted in another thread by ALINWA and prompts this commentary and a following question.

My first 1000 yard HG barrel, a 1.750 brute, was chambered by a well regarded smith on this forum. The barrel was the best ever on that rifle. It won many relays and matches and had a top ten at its first Nationals.

At the time, circa 2003, the smith said I could wrap 0000 steel wool around a brush and short stroke the leade only to remove any burrs left from the reamer. He made it very clear that he does not perform the operation but leaves it up to the client to decide if it should be done.

Well, I did short stroke the leade on that barrel like described, however despite its success, I never did perform that procedure on another barrel.

And now for the question:

Does anyone else perform or recommend this 0000 steel wool short stroking operation on the leade as part of their break-in procedure??
