While sitting with a friend discussing the arrival of his new build, a custom 6.5 x 284 the issue of chamber dimension etc. came up. How long a throat, what jump etc. The smith was a participant in this conversation. He took a loaded round with him from a commercial box of reputable manufacture that had basically the dimensions, and components my buddy was looking for. The smith called the next day, and said the bullet was not what he thought to be a quality bullet. My Friend, and I were a bit taken by this, how could that be? After all they cost 67.00 bucks a box of 20. The problem was the round had 17 thousandths of run out. So we thought maybe the box got banged or something, we should check them all for a fair shake. I took them home to find the best run out at 3 thousandths and the worst at 12 with a sinclair guage. Most where at 10 thousandths run out. The package was not marked from impact or any other visible damage. We took a sample of Nosler new 6.5 x 284 and measured, and found them to be around 2 thousandths. Acceptable.
So what should be expected from a factory round? I don't have any real razzle dazzle equipment, but I can load all day long at 2 or less. Anything above 2 to 5 I use for foul and sighters. We have shot this ammo in other guns with not amazing results it was ok. Never checked run out before. Maybe my ocd is acting up?
