I know how I do my measurements and I know how the german and english proof houses create their "minimum recommendations before reproof", but I thought a thread with comments by experts is in order.
Anyone more qualified than me care to make recommendations on where you like to take bore measurements and how you reconcile a gun with good walls (but a thin area) versus a gun that is overall pretty good (e.g. .027") but pretty slight all around?
I personally hate taking bore measurements because I've got a vise mountable gauge for horizontal use and it takes a lot of tweaking and messing around to make sure i've got it right.
Any constructive thoughts?
