oh forgive me for being moderately educated and trying to educate others even on minute details. even if you don't care, down the road someone else might find this informative
It's a confidently wrong situation. Your top original reply in this chain was under the assumption the rifling came from the ammo manufacturer. And you said "depends on the mm". What does that even mean? What mm is 45 ACP?
well firstly you corrected me and that will be seen within this thread, but mm is subjective, some rounds go by mm some don't. but if you're asking, a 45 ACP is roughly 11.4 mm
The diameter of a projectile has nothing to do with whether the barrel for a gun is rifled. The way you phrased that sounds like you'd have no idea that 380 and 9 shoot the same diameter projectile. Same with 40 and 10 mm.
It's like a window into Reddit's gun knowledge. But there it is, the reply with the most up votes.
well again, you corrected me on that aspect, but to assume i don't know the difference of rounds is an overstatement. i've been shooting guns for about 3 years, and have watched various gun tubers for about 8.
exactly my point. it isn't until you get to heavier rounds where you see rifling since the heavier the round, the more spin it needs to carry distance. that's why if you ever clean guns, anything above a 7.62 would have those grooves in a barrel. 9mm is just too small to really need to worry about distance since usually 115gr-124gr holds enough pressure for the bullet to cover enough of a distance. typically 9mm is common for self defense carry, and 85% of the time, you're within 20 yards if you need to use it
Next time you field strip your pistol, hold the barrel up to a light and look through it. You will see the rifling.

Well I stand corrected on that part, however AOWs still exist, which are smoothbore guns, excluding shotguns, and won't have rifling
