I'm thinking of buying some of these once-fired hulls:
https://www.ballisticproducts.com/mo...tinfo/WINXP1F/
But I want to know exactly what type of hull they are. Would I use the load data from the Win Universal, or the Win Polyformed, or the Win AA (original), or the Win AA HS data? I want to be sure I can use the wads etc that I have around with these hulls.
Does anyone know about these? Ballistic Products hasn't answered my email about it.
