I am in the process of creating the cheapest possible round to cycle a gas fed .308.

My question is will a .308 with a 110 grain bullets cycle a gas fed semi or full auto? NATO specs call for 150 grain bullet. I'm worried that a light bullet will come out of the barrel too fast and not allow a build up of gas pressure needed to cycle the action. I have no experience in this issue.

Powder valley has .308 bullets at about $75/500 bullets. That's the cheapest I have seen.

I don't have the gun yet, so I can't make some rounds and test them. Won't have the gun for about another year, pending ATF approval.
