The premise of the article is that there is a taper to 9mm Luger that creates issues with stacking and feeding, the new 9mm Automatic design cures that. It is an interesting discussion. 9mm Automatic He encourages those who agree with him, to compel the ammunition manufacturers to produce the design, based on the results of his prototype results (and probably the fact that he holds the patent). While I would like to try this ammunition, My 9's have never had a FTF or FTE and I am an "if it ain't broke don't fix it" kind of guy. OTOH, I think my 9's will shoot anything you feed them, I have run everything through them from COR BON to Montana outhouse reloads without any issues. I think it would be a good way to reverse test the theory. If you have a finicky 9mm, a possible take away from the article, there might be some benefit to breaking out the calipers (if you are good enough to measure those tolerances) and seeing if a less tapered round, makes a reliable gun out of it.
