[QUOTE="Mikecr, post: 449638, member: 1521"] It's your tool that's WRONG... If you put that same ammo on either the Sinclair, or NECO, your delusion here would break down pretty quick. Picture a stiff jump rope with both ends pinned while indicating arc very near one PINNED end. This is your Hornady. Does it seem like the best place to measure the diameter of an arc(runout)? Or wouldn't it indicate only a fraction of the arc? YOU ARE SEEING ONLY A SMALL PART OF YOUR RUNOUT. That tool is giving you what you WANT to see, instead of what you DO NOT WANT to see, which I suspect is why it's so popular.. Now you can bend that rope, again very near the indicator, which will of course cause any reading you DESIRE. But unless it reads low runout on a Sinclair, it ain't straight, and you can take that to the bank. I've tested an H&H, with the Sinclair, back & forth, over & over, every which way but loose, because I really really wanted the straightest ammo in the world. In the end I concluded that runout under 5thou off the ogives, as measured on Sinclair, would not even indicate on the H&H. It would barely indicate even with a 10thous' indicator. So I modified the H&H to indicate off the center of the case(center of arc), & with this readings were closer. Then I concluded that very low runout ammo(<1thou), as measured on my Sinclair, was ALWAYS very concentric on the modified H&H. So I didn't need the H&H. I don't care about eccentricity. Ammo can be made straight, but NOT by bending it. It was a waste of money. I care about runout, reducing it, and the Sinclair approach is the 1st step in the right direction. [/QUOTE]
