I once had a winchester Mod 70 varmmint in 22 250. I pushed it to about 1,500 - 2000 or so rounds and gave up on it. Sold it as a donor action to a fellow. I was very careful to tell him that it was pretty shot out and he understood perfectly but then said he never intended to shoot it at all. The throat was so burned out I could not seat 60 gr bullets so that they could find the lands. You culd see the wear by looking into the end of tje receiver. I babied that barrel too. Used a moderate load of 4064 and never let the Barrel get hot. Shot targets nice and slow. Even when heavily worn I could coax 1" or so groups with the right loads.
