    barrel ife is in 1000/1200 rounds full accuracy ( factory accuracy ) perhaps reach 1500 without toobad accuracy

    long bearing bullet , big caliber are very hard on rifling .

    I have one spare barrel ( factory new take off ) stainless for sale at 320 USD !!!!

    good shooting

    Although I can not answer your question specifically, I have observed that the rate of throat erosion is HIGHLY dependant on the number of consecutive rounds fired, or in other words, internal metal temperature.

    I have toasted small/medium bore barrels but ignoring the barrel temperature. Didn't have the time or patients to allow the barrel to cool COMPLETELY.

    Conversely, I have two overbored cartridge guns that I NEVER shoot hot and always allow to fully cool (yes, its a pain in the neck sometimes). Both of them have exceeded the normal expected throat life and still shoot exceptionally well.

    Heat kills throats.
