EverD,
Shooting eiders, I do not suppose you are near Amarillo, Texas, but I think that I have a few 3" paper factory loads left.

As far as roll crimping, I would get some 3.5 inch fired hulls and shorten them to 3 inch, they would roll crimp better.

BUT remember non-tox is a breed of a different cat and may take different propellants as the non-tox travels down the barrel differently than lead.
