Many years back, some bullet-type scientists noticed that 9mm Luger was inaccurate as hell. At least, it was with standard RN ball ammo. For some reason it was quite accurate with most JHP.
Why would this be, they wondered. Could it be the shape of the bullet made the difference? Because, even though there WERE RN hollow points, most 9mm JHPs looked quite a bit like this.
So they made up some solid bullets, with that shape. Low and behold, they also were accurate.
Thus was born the "Truncated Cone" bullet shape.
They found that FMJ TC bullets fed just as well, in un-modified guns, as FMJ RN, and were more accurate.
This discovery was made BEFORE the 40 S&W was invented. Since RN bullets are, compared to TC bullets, extremely inaccurate, why would they bother even making RN for this new round. So, pretty much, they don't.
