Since the good barrel is a 6 and you aren't shooting group right now then I would agree to take it off for the time may come when you will shoot a big group shoot and wish you hadn't burned it up locally.

My first BR barrel, a 1-14 Hart was a very good one. I'm happy with my current one but it isn't the tube the Hart was. Well, it may not be dead yet. We bore scoped it at the winter meeting and Gary Long found about 1" of fire cracking and coppering just ahead of the chamber. Since it was 23" I left it with him and he cut the tennon off(the length of the bad section) and rechambered it. Don't have it yet. The rest of the barrel looked almost new....3500 rounds. Amazing how modest powder capacity and .30 cal bore area seems to increase barrel life substantially over the 6 PPC.

I have a Hart PPC for my gold gun that Ruth Franzius broke in at the Nationals in Mainville last year(shooting a 249-15X for her first big shoot outing with a 6 mm) and picked up two used LV PPC's this winter...just in case we do the super shoot sometime. One is the #1 Panda action of 2003 with a nearly new Shilen. The other a recent RFD, made just before he stopped producing actions with a Krieger. Not sure of the shape of the Krieger as I've been having troubles with getting rings to stay on the bases. I've reached the conclusion that he made the bases to fit a particular set of rings and I can't get either Kelbly or Jewell rings to stay put. Have ordered a set of #1 bases from Kelbly's and hope that cures the problem. Going to borescope the barrel at our first shoot as one of the fellows has a new borescope. At least the crown looks fine.
