In this day and time, I'm amazed that most don't understand all the correlations.
In years past we played with lots of combos to try to find a bit faster speed, at safe pressures, and its amazing how many things change MV and pressure.
I know you say you can't get more speed without more pressure and its true, but some stuff we did, that was roughly pressure tested after the fact showed above "expected" speeds while showing same pressure signs as factory ammo. Per a Chris F whatever those tests were where you glued a testing gadget to the barrel etc...
But so many things can change pressure... hence the safe disclaimer RE start LOW.. below max.
Good read.
