I wonder if cryo treating the barrel before threading would help with that. What do you think?

Markbo. The absolute key is to heat treat. up at 100 degrees and then a cool slow down, while the barrel is still in the blank form, It should be drilled reemed and rifled before heat treating and the rest done after , turning the outer contour the barrel extension and chambering I do know that the guys at keystone are going to heat treat all their threaded type barrels. I have heard through the grapevine that they will soon come out with a threaded type for the 722 in another type of stock but i do not know what kind it will be. I have talked to the warranty guy there and dont get me wrong, he is a huge help whenever i call but he seems reluctant to give too much information or detail about the newer style stocks for them.

Regarding feed issues, I've found that it feeds most reliably if you push the rear of the bolt with your thumb, rather than using the bolt handle. Also, you've probably discovered that ejection is most reliable if you give the bolt a firm rearward flick after raising the handle.

I'm pleased with my 722 Classic, although I've yet to assess its accuracy as it was quite windy on the last trip to the range.

ED, the barrels are attached by first pressing the barrel into the receiver then they are held in place by a allen head set screw in the front receiver leg that is directly in line with a dimple cut on the barrel extension, then they are drilled and a roll pin is installed into the drilled hole. very strong combination
