Recieved my new G23 this past Friday, my first .40 handgun. I currently own two 9mm in addition to the G23, and have previously owned a .45. Can someone tell me why the .40 target rounds have a flat point as opposed to a rounded point on the 9mm and .45 target rounds? This might be a silly question, but again this is my first .40 handgun.

Thanks

Winchester White Box?

Federal and Blazer both have flat nose on the target ammo, I believe WWB is the same. Why?

I think it's to roughly mimic the profile of JHP bullets. It could very well be done to help keep the .40 within the right OAL too. Most of the bullets you buy to reload with are somewhat flat too, although you can find some that are indeed rounded.

I wanted to add, stay away from Winchester White Box 165gr FMJ. It is the absolute most inaccurate junk I've ever shot out of all of them, you are literally wasting your money. Winchester should be ashamed to put this ammo on the market it's so bad. I'm just giving you a heads up!

This is correct. You won't find may RN profiles over 155gr in wt, they are just too long for proper OAL.

The .40 was designed to fit into 9mm-size handguns. Had .40SW used a round-nose bullet, pretty much the whole handgun would have to be re-designed for the longer cartridge or it would've had to be put into .45ACP size handguns and in that case it might as well be the original 10mm. Also, its parent cartridge the 10mm uses the exact same bullets. And both were designed to be used mainly with hollow-points for self-defense loads.

It's a better way to get a heavier bullet with correct OAL and more case space. The 10mm, .40 and 357 auto were designed around HP's. The 9mm and 45ACP were not. If they were designed today, it would make more sense to add 1-2.5mm in case length and use shorter, truncated bullets. There is very little case grabbing a 125 gr. 357 auto bullet packed in a 9x19 seated to the correct OAL, where there is plenty with a "pointy" 124 gr. if that makes any sense.
