Re: PCA-Spectrum bullets
The first time I saw these I thought "wow, that is a terrible idea!!!" now in all honesty, a case is nothing more than a powder container that becomes a gasket. Apparently at the operating pressures these cases see, these plastic ones work as both just like brass. That said, I don't think ill be reloading them any time soon. The whole thing about the plastic having better "memory" than brass is the bizarre. Im not sure what that would bring to the table even if it were true. The fired cases I have don't have enough "memory" to hold a bullet after being fired, so they would have to be sized. I can pinch the neck closed, and it pretty well springs back to round, so I seriously doubt they could be resized. I pulled the plastic portion from the brass base, and they are boxer primed, so they can be reprimed with regular tools.
I will admit that I always assumed that this whole design was meant to be cheaper than producing "disposable" steel or brass cases for high volume shooters who don't reload (aka. the military ect...)
Anybody care to argue against that assumption?
