I have an odd question but humour me because I badly need clarification.

Is it accurate that when you try to insert the .40 cal on the mouth of the barrel (exposed, outer part) you'd notice the FMJ head is actually a tiny wit bigger than it should be.

Just my curiosity that needs confirmation

That's normal.
The right term is muzzle end,
the other side is chamber.

It's true of any modern bullet and a rifled barrel :)

The gases produced by the burning cartridge propellant produce the
immense pressure necessary to force the bullet rapidly through a
barrel that is otherwise too tight for it to fit in.

That is why barrel rifling leaves it's impressions on the sides of a
fired bullet: the bullet is deformed by the barrel's tightness.

If the bullet could just fall freely through the barrel, then much
of the gases would bypass the bullet, bleeding through the surrounding
gap between barrel and bullet, wasting pressure.

Furthermore, the insufficient contact (obduration if you like)
between bullet and barrel rifling would prevent said rifling from
imparting proper spin and stability to the bullet.

Just like doing it to a virgin.

Except that in your case, pressure builds-up in the end rather than in the beginning. ;f;f;f
