Hmmmm sorry Muir it seems that we are at crosed purposes
I will point out on benefit of the undersize .303 britisah brass ..................... I use new R.P brass to make cases for the 6.5x53R which needs to be 0.005" smaller in the web area than the .303 should be the rim is also slightly smaller in diameter
so it actually helps in this one isolated case.
I did have a fair bit of the Winchester 180 Gr SP "white Box" in .303 and yes it shot quite well.
