If I shorten the barrel length then I know the muzzle velocity will be reduced (if the only thing changed is barrel length)

So is there a formula that can be applied to work out the effect?

E.g.

Barrel length (x) = velocity (y)

Barrel length (x-1) = velocity (y-1)

And so on

If feasible then I could possibly play around with load development to regain the lost velocity if required
