Do you use less powder when using Match brass?

I'm reloading for my 308 using 165 spbt, Remington brass, 45gr of H335 powder and match primers. Now I'd like to transfer this load to match brass and since it holds about one grain less powder I have always used one grain less powder in my loads. Is this necessary?

This about a MAX. load and i'm a bit concerned about pressures in my old 788 Remington.
