Isn't anyone surprised that the author of the book stated that modified choke was .005 and full choke was .020 to .030 in 1895? I thought that the chokes were much tighter then, modified being about .020 and full .040. But I don't recall ever seeing an old gun with choke constrictions like that.
What I was wondering why we still use the terms I/C, Mod. and full for chokes, they don't really tell us much. It would be better if we used actual constrictions. But then, even the costrictions throw a different pattern in different guns.
