Roze Distribution has 37 boxes of 500, swaged, 158 grain, 0.357 semi-wad cutter, hollow-point bullets for $51 a box. The price includes shipping.
This bullet is nearly identical to the ones used in The FBI Load for the .38 Special.
I cannot vouch for the BNH of the bullets but assume they are fairly soft. That is, that they are intended for the .38 Special and not .357 Magnum pressures and velocities.
