At one time Hornady made H&H basic brass. This was the belted magnum brass that had not had the neck and shoulder formed. It was the full length cylinder brass,

Does anyone still make this case? Does anyone have a supply of these laying around (and willing to part with them)

Norma makes 45 basic brass Belted H&H size head suitable to makes some interesting cartridges out of.

Thanks. Now to find a dealer in the U.S. The search continues...

just looked at the Norma 45 basic and this is not the case head that I need. The 45 basic is used to make the 45-110 and 45-70 based cartridges. I need the belted magnum basic case

I have 5 boxes of Norma brass that I think is what you want. The box is labeled "Unformed 300 H&H", but is just cylindrical brass with the standard belted magnum head. It is not for making rimmed cases. Let me know if you are interested.
