Does that mean if I find a one hole group using virgin brass with a certain charge of powder at certain speed then the fireformed loads will have to have more powder added to match the speed of the virgin brass load? I know that volume of virgin brass tend to be less than fireformed loads.


In my experience with only three 7mm-08 A.I. rifles in the last seven months, the answer was yes. Load the same fire forming charge in formed brass, there's more case volume, so pressure comes down, and speed comes down.


Just what I thought.
