    Thanks and good points.

    1. I have no issues grinding parting tools, feed rates and cutting speeds for 416

    2. I always leave green when parting and face back to get dimensions right.

    I cut off with a bandsaw on the muzzle end, because Iím taking the barrel out anyway, to reindicate the muzzle. But Iím not buying the deformation theory. Even on the muzzle, you face back .100Ē...

    I turn the tenon .010 short, I grind a right facing tool, with a point that is ~80 degrees (acute), set the compound rest at 90 degrees and plunge into the face 0.010" out from the tenon 0.010" and...

    Agreed, if the bore is concentric to the outside of the barrel, or uniformly eccentric at muzzle and breech. Unfortunately, thats not what I have seen with most blanks.

    You bolt a chuck to it. The TBAS is just an adjustable intermediate between your chuck and headstock.

    It allows you to indicate a bore using a 3 or 6 jaw.

    You arguably still need the copper...

    Itís unlikely epoxy would put stress in the barrel, especially over a short distance. We use epoxy (chockfast) to bed large diesel engines, for that reason.

    This issue I would have with that...

    If you compare the readings you get from running a long stylus in there, to fitting a PTG range rod. You will get two different deviations but which represents the bore? The range rod is referencing...

    I'm going to try that, I dont think T6061 is tough enough.

    Itís not really a test. I just collected data from my normal checks after threading and cutting the bolt interface.

    I put the indicator on three times, during barrel work, and once, facing off the...

    I put together a little data after chambering 6 barrels in the past couple weeks. Here is my setup and what I found.

    Some people use a piece of copper wire between the barrel and chuck so the barrel does not deflect. I use an aluminum ring that I machined and cut with a slitting saw.

    I would properly fit a new or used barrel to the action...my preference being new. A damaged barrel is a perfect excuse to make an accurate rifle.

    It seems small cases approach peak velocity in less barrel length... In some cartridges/powders/bullets sawing a 26" barrel off at 18" only reduced velocity 50 ft/sec from 2700 to 2650 in .308 win....

    I do the action and barrel assembled, bolt out, trigger removed. If I'm doing just a bbl, then I dont spray the thread or shoulder.
