Can't recall seeing a factory loaded round nose version of this cartridge.

Works better in short ejection ports.

I always figured it helped in making it fit in the 9mm frame OAL limits.

I never knew that. You guys talked me into a larger Caliber Semi-auto when I sort of defended the .380. So I won some bucks in a Super Bowl Pool and it was burning a hole in my Pocket. I ordered an S&W SD40 yesterday. It was very reasonable and no larger than my 9MM SD9. I guess I'll have to do a little research on a bullet Any of them should I avoid?

Probably because it's daddy, the 10mm, was designed with a flat point, which disrupts tissue much better than a RN. The Germans came out with a truncated cone bullet for the 9mm and it was far superior to the round nose. It caused quite an uproar with the allies in WWI and Germany returned to the RN.
Remember, back in the '80's HPs were just coming into vogue and weren't as reliable as what we have today.

Could be history. The 40 caliber is nothing new. The 38-40 is actually a 40 cal and it was a necked down 44-40 in the late 1800's an thru about 1940 in the US. All of those bullets were either RN or RN/FP .If I could find some 40 cal bullets with a cannelure I would be loading them

I suspect it's to keep the OAL of the cartridge short enough to work on 9mm frames (the whole reason for the .40 in the first place was to fit in the 9mm "envelope" of pistols.)
A roundnosed bullet is too long to fit in the case AND magazine.

A roundnosed bullet is too long to fit in the case AND magazine. This right here is the correct answer! It's to help ensure its fits in the existing 9mm frame pistols. Mark in GA

It wouldn't be a roll crimp but it should work pretty well in the 38-40 I'd think.

Never thought about the 40S$W crimp,I bought a 38-40 Lee Factory crimper, but it would not crimp heavy enough for the Marlin 94 I have. You have to be pretty careful with the 38-40 case. The neck is so thin,you can end up getting a bulge pretty easily. The Colt SA I have,I need to use .403 bullets in it and all 40 cals as I remember are .401. They could be .400, but I am not sure. The FMJ ones I tried pretty much rattled down the barrel.The ones I loaded up for the Marlin, using that Lee factory crimp, would get pushed down into the case when loaded into the tube magazine, but .40 diameter bullets work fine in it

Wasn't the 40 S&W designed around hollow point bullets?
I would think that would explain OAL and shape of fmj bullets.

I would think that would explain OAL and shape of fmj bullets. And finally we have a WINNER! By the late 70's, pistol design had evolved to straighter feed profiles to accommodate hollow points; and by the early 90's, those hollow points were pretty damned good. It is only in recent times some believed a pistol bullet should expand after going through sheet metal, auto glass etc. If my pistol bullet has been slowed by those kind of obstacles, I don't want it to parachute when it hits the asshat I was shooting at. The bullet will already be ragged on the end and I'm happy if it drives on through him.

Could be better than the roll crimp Lee uses given the thin case neck. If somebody close by has one to borrow it'd be interesting to see. Actually they don't cost a lot anyway. Have to use it in a separate step but that might be best too.

I think they are only about $13.
