Don't forget, that is with an entire mechbox made of modify parts, it would probably have a very good air-seal, better then most guns.
If you looking for a little over 350, i would use a M100+ tight-bore barrel
Although that chart is a good base point to compare the velocity between different springs, it can't really be used to predict an accurate velocity from any given spring. There are too many other variables in a gun that produce its given FPS.
