Happy birthday Larry

Went with a friend to a friends private range and work on indexing some bullets.
Three tuner movement and got them all into one hole. Heat wasn't bad and humidity good . I hope I can remember what I did Saturday . Larry

How do you know which way to index bullets?

Must have not worked well, you're still with us.

It kind of makes sense that a 6 o'clock index could be a little easier on the front bag.

I'll admit, I let you drag me into the gutter. I apologize to the forum members.

Does anyone know on the indexing points,
how far the groups move from POI,
several hundreds OR inches from POI?

Trying to learn, what are you guys indexing at 12.or 6 clock? Are you checking the inner diameter of the muzzle with a indicator and looking for run-out ?.

The indexing is done with smiths that use a range rod or simulator rod . They adjust the barrel to where it is straight down the bore . The muzzle end when the rod is installed normally moves off center from the chamber end . They time it at 12 or 6 . Then they headspace when the barrel to the action where the muzzle ends up At 6 or 12. The other thing that happens all the threading and chambering is done of the true bore .
Does it make a difference -- It does to me.

So you have range rods in the chamber and muzzle ends and are indicating off of these, correct? And when the muzzle end is off by a certain amount you mark that point on the barrel and then use that for the 12 or 6 o'clock position?
