What is the proper or good bore for an 03A3?

I have an arsenal rebuild (one punch mark) and shows no wear on the green parker.

Unfortunately, doing a bullet test in the bore with commercial 150gr ammo.
Results are bullet is 1/16 to 1/32 from the case.

What is the reasonable bore diameter? As a welder and machinist, I have the tools and ability to measure these bores
properly.

What should I be looking for?

Many Thanks
