I noticed on the Parker hang tag, it states; "brass shell should never be used with nitro powder, brass shells may be used with black powder."
Why is that?

Not 100% sure on this but I think it had a lot to do with available primers of the day. Many of the primers which the brass shells took were sim[ply not hot enough to ignite most smokeless powders. When I began loading shotshells back in the '50's Alacan recommended their brass shells with Berdan primers for use with Dupont Bulk smokeless as well as some loads of Red Dot & an Italian imported Smokeless powder known as Nike. I successfully loaded 20 gauge brass hulls with both. Lyman essentially recommended the domestic brass hulls using large pistol primers for the same powders & stated the Berdan primed brass could be drilled out to take a 209 shotshell primer & be used with the progressive powders. Alcan also imported a line of brass in 12 gauge only as I recall which was made for the Rem #57 primer which could be loaded with the progressive powders.
In all cases when using smokeless it was imperative to get a good Top Wad seal to ensure proper combustion.
