What is the case volumes for a 300 NM Imp version with a 30*, 32.5*, 35*, 37.5* and 40* shoulder?

Any advantage of increasing the shoulder diameter and reducing body taper instead of going with the orginal? Not worried about a increase in case volume.

When using Quickload you are told to check case capacity with a case fired in your chamber.

Not trying to be impolite but chambers and cases do vary in size/capacity.

No problem and I’m fully aware of the difference in case volumes. Although body taper etc. will also influence the volume, one will at least get some sort of idea and with enough data be able to identify some sort of trend.
