I've had the rifle for at least 20 years and about 20,000 rounds through the OE barrel plus whatever the previous owner put through it, over the years I've upgraded it and got it shooting great, to the point where I could go out today put some rounds through it, clean it, shake the dust off of it a month later and put rounds through the same hole from last time. A year and half to two years ago it lost its edge and got to the point I couldn't make consistent hits at 600 yards, finally ordered a new barrel for it in March and got it 2 weeks ago. Finished the break in today and my last group I shot at 600 was 2 inches(I'm guessing, didn't bring my tape measure down with me).
Out of all the loads I was shooting today, around 80 rounds, 16 different loads with blem bullets the last one is the one that surprised me. I'll have pictures to back up my claim next time out
