[QUOTE="shortgrass, post: 1078808, member: 24284"] If JP says their barrels are good for 40,000rds, they must be Melonite/Black Nitride treated. Me,,, I want to know who made the barrel . As for "how long will it last",,,, that depends on how it's taken care of and how it's fired. Rapid fire generats heat,, heat destroys barrel steel. All barrel makers basically use the same steels. Either 416R stainless or chrome moly in the 4140-4150 range. Barrels are the 'expendable' part of ay firearm, I expect to have to change one out now and then. Actions don't wear out (unless they're abused), triggers don't wear out, and stocks don't wear out,,, barrels will and do. 40,000 rds. is a lot, even for a barrel that's been Melonite/Blk. Nitride treated. [/QUOTE]
