guys, I am hoping you have some assistance for me...
I have a 260, 308 and 338. I have been running the 260 and 308 for a while - runs 100% great (a dream to shoot the 260). I had been waiting on a bolt for the 338. I finally got one, but right after I got it and put it into the chassis it really didn't feel anywhere near as smooth as the .308 bolt.
I called DTA and sent my bolt back in after explaining the issue.
I just got the bolt back from DTA - looks like the same bolt, but I put it into the chassis and worked it like 20 times. After doing so, there are a lot of metal shavings in the bolt raceway near the barrel shroud. Below is a picture.
To double check, I removed the bolt, cleaned the channel, ran the .308 bolt 30 times - checked - totally clean. Put in the .338 bolt and ran it 20 times - lots of fresh new metal shavings.
Any ideas?
