Translation of :Polish needed

In the .38 special bullet shell color means the power of the cartridge: white - 107 J, yellow - 158 J, blue - 211 J. I think the same for 9x18.

Hooke - I am familiar with the .38 Special loads. While I don’t collect them, my friend Steve Fuller brought back a great many of them from a trip to Poland years ago, and I had some in my dupes for awhile. I have never heard of any of the 9 x 18 other than white, and the yellow one, which never seems to have reach much serial production, if any.
