My dad had one of these and it is now mine. From what he told me, the Zouave was made to shoot miniballs the best. I'm not sure about yours, but the rifle lands and groves in mine are extremely wide. About 4 times wider than what I would consider normal. I was thinking about hunting with this gun too and was going to shoot the mini.

I am interested to see how it turns out for you. If you could, let me know what you have the best luck with and how the PRB turns out.
