Agree with Peter.
Titegroup serves my needs very well as a propellant, but is hard to work with. It is dark, dense, and irregular. Hard to tell whether or how much is in the case with a quick look as I set the bullet. I am now loading with HP38 which is almost silvery and easy to spot.
I found Titegroup to be less position sensitive than 231 but worse than 700X. But 700X is a large flake powder and I have had trouble with its metering in light target loads. I am anxiously awaiting Trail Boss for Cowboy ammo.
