[QUOTE="J E Custom, post: 349459, member: 2736"] If you log on to the Lilja web site and look in FAQ you will hear just the oppsite about barres life so who do you believe. All I can go by is the cut rifle barrels that I have owned did not appear to last as long as the buttoned barrels "BUT" I have never owned two rifles of the same caliber to do a barrel to barrel comparison and the only cut rifle barrels I personaly have/had were in 7/08.7STW and 338. the 7/08 went away (lost some of its accuracy)with less than 500 rounds down the tube. The 7STW Had less than 400 (Hard) shots through it befor I had to retire it, And the 338 has not had enough rounds through it to tell. But the buttoned barrels have all done better, New 7/08 800 rounds and still shooting, the 7 RUM has exceeded the 7 STWs round count and is still shooting great. Many years ago I started shooting NRA high power matches so I bought a 40X range master that had a buttoned Hart stainless barrel against everyone's advice and after 50 years and over 25,000 rounds it will still shoot sub 1/2 MOA groups with iron sights. I realize that the 308 is not hard on barrels but 25,000 rounds is. and the real test is my 30/378. With a 122gr load of H50bmg behind a 200gr bullet barrel life should be short but so far with years of shooting no signs of accuracy loss has appeared. Most of the better military rifles have chrome lined barrels for wear and my understanding of the buttoned process it aligns the grain structure improving the wear characteristics on the bore surface. Is one better than the other ? I could not make that call because of lack of extensive data. I just know what I have experienced. PS; I still use Both cut and buttoned barrels and it just depends on what the person having the rifle built wants. J E CUSTOM [/QUOTE]
