So, I'm trying to warp (sic) my tiny mind around the idea of measuring case volume. my concern is going from one brand of brass to another, or old brass to new brass, all within the same cartridge, and determining case volume before powder loading and velocity testing.
Does anyone have some thumb-nail suggestions for consistent accurate case-volume measuring?
I know that working up a load with new weight-sorted brass all of the same headstamp is by far the best-practice for consistent case volume control. But I'm getting more and more into obsolete cartridges, and NOS brass for those is getting more and more difficult to find, and of course the cost of powder to play with keeps going up... you know the story,
Thanks, for sharing Your considered experiences,
Jeff
