Unique is probably the slowest powder that will give good results across the full range of 38/357 loads.
3.5grs under 148gr or 158gr bullets makes very mild target loads, 4.5-5.0/158 is close to a factory 38 duplicate.
6.0/125 or 5.5/158 are great +P loads.
In 357 cases 6.5/158 is a good everyday midrange load and 9.7/125 and 8.0/158 are full power magnum loads at close to factory velocities for each weight.
Anything slower like 2400 or 4227 won't perform well with lighter loads and W296/H110 are only suitable for full pressure magnum loads.
