Walruskid1 , if you cast your own ball and don't want to spend much on a mould pick up a mini ball mold from mid shouth shooters supply around 15.00 but find out your bore diam first the best accuracy with mini balls is ball .002 under bore diam lube the grooves only and DO NOT lube the hollow base start with 35 grains of 2fg black and work up ,or if you have 3fg start also with 35 grains if you don't care about how much you spend on bullets, dixie gun works sells them as well as track of the wolf , also from mid south they have lyman and rcbs steel moulds more money but quality lyman sells a wad cutter type desined for the zouve that was particularly accurate I think Papabear knows the one I'm talking about try these ideas first but if you want to shoot round balls your rear site will have ti be cut if you have a dremel tool put two cutting disks in and cut down a little too much then will have to file the front site down to lower the piont of aim. wish you were closer
I'd get that thing shooting straight. good luck and have fun with the zouave. bb75
