Well- it creates a hole to let the bullets and noise out.....

But expect that was not your real question. Do you mean counterboring the muzzle? Older rifles that have excessive wear/damage to the rifling at the muzzle are frequently sadly inaccurate- bad cleaning, erosion from corrosive ammo, etc. By boring out the last inch or so, the bad rifling is removed, and SOME of the accuracy may return. The old rifling did not wear evenly- but when cleaned up, the uneveness was disposed of, and remaining rifling evenly contacts the bullet.

OTOH, crystal ball in still in shop for calibration and oil change- if I missed your question, can you expand on it a bit?

Hmmm- ya got me there. Have seen SLIDE bored to deal with sloppy barrel fit or misalignment, when adding an oversized match bushing. Usually not for a duty/carry weapon- nor is a compensator. IMHO. Bells and whistles for MAX accuracy may degrade RELIABILTY to some degree.

Then again, it might just be HollyWeird doing their usual great job.

Do you mean reboring? Reboring removes bore defects, which improves accuracy, and it also increases the bore diameter which changes the calibre. ie .22 into .223.

Thinking about that movie, I think he is talking about reboring. Also, a hand finished bore is smoother and more consistent than a factory one, again improving accuracy. So many things affect accuracy.
