I have a derringer like that and it seems that it actually shoots harder with 10 or 15 grains of powder than it does with 25 or 30. If you put 30 or more grains of powder in it, half of that extremely short barrel becomes chamber and the loss of usable barrel length seems to offset the benefit of the higher powder charge.
I have gotten good velocity out of it by using a very small load of 10 grains of 4fg.
