Well, I'm not sure why you are taper crimping -- a .32 H&R Mag die will roll crimp. That's what I'm using. (Lee dies) I can roll crimp enough to clamp that little pill in there with no trouble whatsoever. I can even roll crimp enough to keep a plated bullet in there without cutting through the razor-thin plating.

I like the idea of calling Sierra but maybe I'm old fashioned... I don't have any Sierra .312" bullets on hand. So I'd be calling them for advice using Winchester bullets and Alliant powder. Think it's cool to call them when not using any of their products?

I did see that 71 grain data from the ST article. I sure don't have that powder!
