Gold Dot 38 is kinda an older standard in 38 special. Doesn't work poorly, but for the same price there is a new better?
If you haven't checked into it, HST 38 is essentially 100% open at the mouth and goes deeper with greater expansion than Gold Dot.
Both Gold Dot (Speer) and HST (Federal) are owned by Vista Outdoors.
I think HST bests Gold Dot here for both qualities you want.
THAT said, HST performs poorly in 380, just like Gold Dot does. In 380, the same owned company Federal Deep 380 is probably the best 380 round ever made.
