I have a Lilja barrel. 12x chambered in 300 RUM. There are roughly 1000 shots down the pipe. Barrel still held sub .5MOA the last time I shot it. My questions are these: Do you think this barrel has had enough shots through it to make it worthless for another project? What I would like to do is have it cut down and rechambered for a 308 win. It appears that I would be cutting off right at 1.75" ffrom the breech end. (1.75" of rifled barrel that is.) Is this enough to get rid of any throat errosion or does erossion permiate farther down the barrel? Even if the errosion could be cut away, would the high heat from the past make the rest of the barrel (non throat) worn out or compromised for accuracy?
