The Western 1 3/8 ounce .

More of the 1 3/8 ounce .

Please, don't shoot collectible ammunition. Quite often, the primers fail anyway.

:duck:

Only one way to find out :whistle::rotf:

Wow. Nash Buckingham's favorite load. I haven't seen a box of those on Ward's auction for years. I wonder how much they would bring there.

What is 4K?

Do you mean '4L'? The 'L' indicates Lubaloy, which was Western's tradename for copper plated shot and bullets..

The box of 1 5/8 ounce loads are stamped "4K" on top while the 1 3/8 ounce are stamped "4L" on top .

Ooops!

:whistle:

Those Winchester LEADER Super-Speed shells with the 4K (KopperKlad) shot are extremely rare and must have only been offered very briefly. None of the Winchester shotshell paper I have from 1931 to 41 shows that load. The only offering of KopperKlad shot in the Winchester paper that I have is in REPEATER Handicap Trap Loads in the early 1930s and the RANGER Handicap Trap Loads in the later 1930s.

By the way, I can recall that somewhere in a previous post I said there was no such thing as a Winchester 12-gauge 3-inch Super-Speed with coppered shot. Never say never! Me eating crow!
