One thing people should remember.
This is the Ozymandias bullet catch:
YouTube video
Laurie is using a Smith and Wesson Model 10:

That has a muzzle velocity of 290m/s:

OTOH, Vanessa was shot by Beretta 92FS (I am assuming here, btw, so feel free to correct this point of mine:
http://www.imfdb.org/wiki/Deadpool_2
Berettas have a muzzle velocity of 381m/s:

TL;DR: Even if we say that Wade's speed was SLIGHTLY faster based on his reactions, we now have to MASSIVELY upgrade this because he was reacting to a bullet that was ~100 metres per second faster than Laurie's revolver bullet.
Edit: and in THIS scene:
YouTube video
(which, incidentally, I saw filming of, by-the-by) Cable is wielding a Walther PPQ:

Cross checking with:
https://www.personaldefenseworld.com/2017/09/walther-q5-match-pistol/
Gives me an 'average' muzzle velocity of 395 meters per second.
And Wade slices that bullet in half.
