Thanks LocknLoad- I'll check out their website. Since the initial posting I've recieved helpful advice plus purchased (at very fair cost) a mould from one member and a small supply of minie's from another. This forum is great! Had my Snider out for a look yesterday and I can't wait to give it a try. While it's not perfect cosmetically, the bore is like a mirror with good looking rifling, action tight, etc (LSA, 1871, MkIII). Thanks again to everyone!
