Tom,
To not answer your question;
I've got/had four of Beyer's barrels. A factory contour, two 0.7??" and a 0.920" contour.
They have all fed & functioned well (all in 22 LR I will add).
No complaints, except the factory contour barrel had an incredible change of POI with the addition of a suppressor. If a suppressor is not in your future and you were chasing the ultimate ultralight 10-22 it would be a good choice.
If weight is not a concern and looking for the best accuracy, I would look at an all steel barrel... Kidd, Fedderson (do they even make a 17 HM2?), or VQ, over a an aluminum shrouded barrel.
I spoke to Clint (Beyer) and I have no doubt if there was an issue He would do the right thing. He replaced the factory contour for me at no charge.
