finally got my upper out for break-in using factory Hornady ammo (white box). FWIW, I ran a cleaning patch down the bore after each of the first 5 rounds, then after every 5th until 25 total, then every 10th until session was over. First 10 rounds or so experienced some extraction issues, but as the day wore on the issues went away. Not real impressed with the ammo, even considering the barrel was new. Towards the end of my shooting session (100 rounds to generate brass), groups were +/- 2" at 100 yards. I expect handloads to improve group size.
This is my 3rd upper from Sanders Armory. Build quality on all is excellent and customer service is outstanding.
