Yeah, problem children can drive you NUTS.
Had a barrel like that. It would not shoot ANYTHING like it should, I found a load that was "functional" in I'd get four out of five in the "tiny group," but still, out P-Dogging I'd not know if EYE missed or the GUN missed.
Then, I got so mad I attacked the barrel with valve compound, I was a tired puppy when I was done being mad. Well -- then I shot another load that was "gopher" class (this was a 22BR) and it was drilling holes with that, and ONLY that.
Eventually, I took that tube off, and later when I wanted a Fireball, that tube was the victim (hey, it was free scrap metal at that point). Well, it's GREAT as a Fireball. Go figure.
