Well....Ifin you can find any Red Dot, I've loaded many many (1000's) of lead bullets all the way from 38's, 44 Specials, and 45 Colts with Red Dot with great success and good accuracy in the power level that CAS is shot. I've never used it myself, but have read of loaders using Green Dot also. Can't recall if its faster or slower in burn rate than its Red cousin, but in the ball park.
Winchester 231 works well also (many many rounds loaded with it) if it is still available or Hodgdon HP38 which it and 231 are basically the same powder. As I mentioned in an earlier post Titegroup works well, have loaded it some in 38 Spec, mostly in 45 Colt and 45 ACP. It is regarded to be position insensitive which works well in large cases. I never noticed any problems back in the day with light loads of Bullseye, 231, Red Dot, HP38, etc in 38 Spec rounds, esp shooting in any of my Police Combat or PPC days or any CAS type ranges/shooting. These ranges and the type of shooting isn't like trying to get real tight groups as if paper punching from a rest. If any of these powders can be found, you won't be disappointed. (edited)
