Chambering the same round multiple times?

[Arthur Dent]

Bullet setback my a$$. I don't care what anyone says, these are the results from my service weapon using my issued ammo with no allterior motive to skew results. My bullets grew!
The pics are in the order they came out of my gun as of Monday morning when I got home off shift.
Pic #1 was in the chamber followed in order as they came outta my mag. I'm gonna get with my firearms instructor so I can get the exact date these rounds went in my mag.

Remember pic one and two get cycled between daily, 3 and 4 haven't been chambered and went straight from a factory box into my mag.

I had that happen to the same round that was re-chambered several times because I would unload it for dry fire practice. When I noticed that it was visibly longer than the next round I fired it because I was already at the range.
