Never seen sights on a 12 bore. Doesn’t it get in the way? Unless you’re not shooting small game?

Fair enough, I never quite got used to how they measured air temperature in Celsius and pool temperatures in Fahrenheit in Quebec. Eventually you get used to those idiosyncrasies.

I’m curious as to why you think the metric system is superior. I came to the conclusion that it’s just as random as any other system. A lot of things don’t fit nicely in the metric system: absolute zero, the number or atoms in a mole, the energy contained in an electron, Reynolds’ number, Boltzmann constant… My critic of the metric system would be that people get to think that everything fits nicely in a 10x10 box, physics will constantly prove you that you’re forcing square pegs into round holes.
