I'd try some of the cast bullet data for those powders. Just keep in mind that you should be very careful approaching the maximum listed loads for them. Cast lead bullets generate, usually, less pressure than jacketed bullets.
For Unique with a 122 gr. cast bullet, starting load is 13 grs. for 1824 and max is 18 grs. for 2207 fps.
For 2400, starting load is 18 grs. for 1685 fps. and max is 32 grs. for 2617 fps.
Frankly, since maximum for a 110 gr. jacketed bullet with IMR 4227 is also 32 grs., I'd stay away from the maximum load listed here with 2400. E
