Thanks. I read the other thread in Boolits. Is the bascule the same as the knuckle or the surface where the forearm touches the action?
So is the nominal size for 13 ga .710 and the 13/1 gage made .007 larger or do the increments vary by guage? I assume these gages are made to measure from the chamber so there would be no interference from any choking.
I also read about the French and German set triggers. This gun has the German type I guess as I can't move the front trigger forward a bit to set the back one. The adjusting screw is on the back of the front trigger. But I don't get much, if any, reduction in trigger pull when I pull the back trigger after the front.
