Changing zero distance - does it do anything?

AS the title - I noticed there are controls for changing the zero distance of a weapon - page up/down for a keyboard by default.

Does this actually do anything??

I’ve tried playing around with it in practice and games - haven’t noticed any effect.

For rifles I havent seen much effect at all either. Perhaps something like a PIAT could benefit from it.

I also feel the games dispersion system is enough to make shots feel as though you never even adjusted them.

Ah - of course you do use it for PIAT and Pzfaust to change the sight picture - I’d forgotten that since they are so little used!!

And all same AT weapon.

Yeah I only use this for AT weapons, tho it would be cool to see it apply to snipers too. I have my binded to scroll wheel.
