The 9mm Automatic
A better 9mm cartridge. Apparently, it’s not a tapered round and that prevents nosedives. I was unaware that that problem occurred with significant regularity.
Remember, I do this to entertain me, not you.

That lack of taper may add extraction issues. Time will tell….well probably not since odd duck cartridges like this rarely are seen in the wild.

He has a solid engineering point, but commercial momentum for 9×19 is so significant that it’s largely academic I suppose.

+ 1 for Weer’d. Straight walled are more likely to jam in a dirty chamber too. The exaggerated taper is one reason an AK is so reliable. If you wonder why taper matters, try stacking cups that are tapered. Imagine how hard it would be if they were straight walled and one only a few thousandths of an inch different in diameter.

I think I would rather just design a follower that fixes the problem rather than retooling…
Its like choosing a bicycle to ride down the block to ride down to the corner store. Do you need one that costs $2000 or would one from walmart do just as well for a lot less money..

Dang it, now they’ve gone and done it. They’ve validated the left.
We now have automatic bullets.

Looks like someone with too much free time on their hands.
Use the right magazine for your guns and they’ll work. Even the straight 33 rounders run flawlessly in a Glock.
He used a .38 SA magazine for his tests …
Please …

Exactly, Calimero — he is also using a customized, mixed parts 9x19mm 1911 as his test piece, not a caliber/model combo I’m aware of having a reputation for flawless functioning.

I wonder if they were tapered slightly originally so they would fit onto a slightly curved stripper clip. The picture of the rounds lined up and curved made me think that could be the case.
