Having sold a allot of once fired range brass I can say first hand how much of a pain in the A$$ the SPP 45's are to sort. I really wish the ammo companies would have stuck to the same old same old. Yes I did it anyway but it was time consuming! I also had to research into the ballistics and "if" they where ok to reload. All info I found on them indicated they loaded the same as LPP 45's aside from the obvious smaller primer.
I did have trouble selling them as many people could not get over the change and would wait till I had LPP 45's in stock over buying SPP cases.
I am pretty sure I still have a few hundred of them somewhere?
