I shot at the range this past Sunday and the shooter next to me was shooting a 6.5x55 AI in a Savage action and the barrel was treated / coated with Nitride inside and out. This shooter claims that he should get 2-3 times the barrel life with this treatment. He said the he needed a little less powder now with the barrel treated to get to the same velocity as before the treatment. He was hitting the steel plates consistantly out to 700 yards with this set up. Putting a coating inside the barrel on the rifleing seems counter intuitive to me, but for $80 it seems like it might be worth a try if accuracy does not suffer. Please weigh in on this.
