Inconsistant loaded round COL?

[Fitch]

I have a gauge made out of a piece of barrel that was cut off during the building process. Standard procedure for every rifle I build.

If you have the chamber reamer and a lathe I'd think you should be able to make your own "bushings" for the Tubbs BSC tool in a few minutes out of the end pieces from the barrel blank.

What I don't understand is how you get the seating die to push on the bullet so it seats the ogive contact point in the same place.

That said, I don't seat that close, 0.020" minimum clearance to the lands in hunting rifles.
