The thing is ...
I've seen 2 barrels that were done with Plum Brown and one old Colonial Era rifle that was originally rust treated.
To be honest ... I can't really tell the difference between the two. The Plum Brown is a
HOT process, and
not a
COLD one. You have to heat the metal to around 250 to 300 degrees and apply the compound. To me ... it's a cheap trick for rusting modern barrels, but it looks good from what I've seen.
I'm kind of leaning towards the Plum Brown just for the authentic look of it. At least with the Plum Brown I can control it somewhat. Unlike leaving my barrel in the yard for a few weeks.
