I could be wrong cheese, but I believe around %36 because it's just too saturated.  HCl is a gas that is Cl- and H3O+ when dissolved in water.  If one were to shoot for higher concentrations it would simply evaporate until it reached that stable equilibrium again.  You can buy the gas though.

Who wants to play cops and dope fiends?

1 kg of water saturated with hydrogen chloride at 15c forms 1.75 kg of 43% solution, density 1.231.

By saturating a strongly cooled solution with the gas (HCl) three solid hydrates are formed : HCl,H2O (mp -15.35c), HCl,2H2O (mp -17.7c) and HCl,3H2O (mp -24.4c).

Umm, how interesting !!
