This is off topic but now that is has been mentioned twice...
John and MagnumManiac,
What chamberings are you guys setting back and rechambering? Have either of you bore scoped the barrel before and after? I would think there would still be an area of heat damaged rifling in front of the new chamber. I have read the second throat will not last as long as the original. I would imagine is has to do with the fact the rifling is already heat damaged.
Have either of you setback and rechambered a barrel that was "shot out" or are you doing it for a barrel that lost its competitive edge?
I have several barrel that are "shot out". One in particular is a Bartlein in 6mm-284. I considered cutting of several inches and rechambering but have thought it is a waste of effort as the bore scope shows crazing and cracking up the bore for at least 10".
