[BUG] T2 Weapons Increased firing rate when using higher tickrate

[rats4final]

Describe the bug
I'm not entirely sure but i feel that the t2 weapons fire quite a bit faster when using higher tickrates, this becomes a problem when you have a vanilla server(and want to have zm as well if anyone wants to play with !match) but with 100 tickrate enabled, as this makes survivors melt the tank with bullets specially with t2 shotguns and the military sniper, I'm guessing this is because of l4d2's 30 tick nature, so any fix or pointing in the right direction would be appreciated.
To Reproduce
Steps to reproduce the behavior:

1. Create a new server and enable the tickrate flag to a higher one
2. Use a t2 weapon
3. See error

Server Operating System (if applicable):

• Windows 10

Additional context
I saw there was a similar problem with the dual pistols and a fix was applied, maybe that is the direction to look to apply a similar fix, I have been looking this repo for a while, and I would try and fix this myself but I'm mostly a web dev so I have not much experience with sourcemod scripting.
