I've had good results with about 3.0-3.5 grs. of Unique and a 115 grain bullet in my .32 Long CF. I've also played with round balls and the same load and had fun. 
I took a re-de capper with me on one trip to the range, along with a homemade scoop that held my charge. Used the same case all day long by just priming it again and another charge, then topping it with a round ball. It was a blast to plink this way, and more accurate than I thought it would be too.
