I remember when businesses paid workers a livable wage! Dell has its headquarters right here in Round Rock, TX. They USED to do a lot of manufacturing here too. Today the parking lots at their campus are largely empty. The local airport was shut down, sold and the land used by Dell to build manufacturing facilities 15 years ago. Those were closed not long after start up, and manufacturing moved to China.
If you can't earn a livable wage, how are you going to afford a new computer every 5 years? In Texas, if you work at a job where you are tipped, the employer doesn't have to pay Fed minimum wage, they pay way less, $2.50 per hour which was as I recall, was a 1975 fed min wage.
The beginning of the end of "made in USA" started with employers cutting wages, not giveing cost of living increases, and Congress refusing to raise the Fed Minimum wage. In many other countries businesses pay well, give generous sick leave and medical care, maternity leave, and still make good money and build good products. What is it about America that businesses can't figure that out?
Back to OP question: Here is a photo using the Teslong in my Shilen Match barrel. These grooves show up in several places down the barrel, apparently made during the initial boring operation. The barrel still shoots better than I can, so apparently not adversely affecting accuracy.
