Dave, I though I would mention two things, one is that if you would like an accelerated test ammonia will work fast that would really show any differences in a hurry, the other is I have had several of the group in our club get into a rust problem because they clean the barrel with copper or plastic remover and did not oil it or get all of the remover off, I thought one piece that had been cleaned this way and left unprotected might educated some of the newer people. I think your test is a wonderful idea. And I appreciate your effort and dedication. Lee
