[QUOTE="ARlife4me, post: 3058652, member: 105694"] And you don't think cooler burning powders gives more barrel life. There is lines where the "both can be true" will cross and less that both will happen at the same time (given which cartridge is used). What I can state for a fact is about overbore cartridges (264wm to be more precise) is accuracy will be accurate beyond those 800-1,200 round before accuracy is lost to bed. According to Sierra data I'm 1/2gr over max (61.3gr imr4831) with 140Sbt in a pre64 mod70 ('61 to be exact). I've shot over 2,500 rounds (most being that same load) and still accurate enough for hunting (never checked against prs type/style). With the universe helping some snd against others, many things are possible. Winchester won't replace the barrel if it shoots less than 1.25moa (could be 1.5moa, but need to call again). Throat looks horrible as southern Arizona pavement and rough as pavement between El Reno and Yukon OK. [/QUOTE]
