[QUOTE="dok7mm, post: 1912934, member: 90080"] I have run 2 nitrided barrels, each set up on two SwitchLug actions, and compared them against two non- nitrided. One was a 6.5 Sherman, the other a 7STW. All four barrels were Bartlein 3Bs. I checked the throat erosion every 100 rds fired and switched barrels. Used the Wheeler method and same bullets to verify lands movement. It was not a scientific test, but I was trying to get info on whether it was worth the extra money. Both nitrided barrels had a slight advantage at 400 rounds on both rifles. I have not shot the STW except for hunting, so I removed it from testing. At 700 rds on the 6.5 Sherman, the non- nitrided barrel showed noticeable less erosion than the nitrided barrel. The nitrided barrel showed more fire cracking. I ended the testing at that point and only use the nitrided for fire forming. 980 rds on the non-nitrided 6.5 Sherman and I'm still shooting it, just a bit longer to clean it. I will not nitride another barrel as it was not worth it in the long run, but I do prefer nitrided actions. Sorry for bumping the OP's thread. [/QUOTE]
