5/16 x 27 is hardly “standard”… it’s an annoying oddball thread that feels only useful for preventing me from grabbing a tap from my tool box and tapping a nice hardwood dowel to make a one piece shotgun rod! I would love to know the history of how that odd threading became “standard”.

I already need an adapter to use a shotgun brush on a rifle rod, so… it’s just a different adapter.

Face it, fellas. It’s not just China that uses the metric system, it’s the entire world.

Let’s look at the kilometer. 1000 meters in a kilometer. 100 cm in a meter. 10mm in a cm.

The mile: 8 furlongs per mile, the number of farm fields am English king decreed. 220 yards per furlong, the length the average English ox can plow a row before it needs rest and turns around, determining length of a plowed field. 3 feet per yard, based on the kings foot and arm. 12 inches per foot, based on the kings thumb. That’s a convenient 5280 feet per mile.

It’s a huge waste of time. But we insist on not improving.
