Methinks it has more to do with the steep feed ramp affecting seating.
Funny, then, that these problems and *phase three failures to feed* have not been as frequently observed in handguns chambered for the .357 SIG, which uses the .40 S&W cartridge case as its parent dimensions, and usually utilizes the same feed ramp and magazine as the .40 guns, with just a change of barrel [and sometimes, recoil spring] to effect the conversion.
IMHO, it's exactly that - "setback"
I've run into the same problem chambering the same "carry" .45 ACP JHP cartridge in my 1911 over and over after cleanings, range trips, etc. Eventually, I noticed the round was much shorter than the others and pulled it from service.
Sooner or later, the spring-assisted slamming of the bullet nose into the feed ramp drives the bullet back into the case.
Lesson 1: Rotate your carry ammo in the magazine often
Lesson 2: Inspect and measure your carry ammo occasionally
