looks like fun.....I take it you HAVE TO use 1/2oz for the steel targets???? 3/4oz is just better in everyway.... it SHOULD work well with black powder as it wont be honking along.....but that said be aware the wee 410 is more sensitive to change than any other guage...all of mine have hated #6 shot with vengence but #4 lovely tight patterns...best of all is a mixture of all sorts of sizes....
look forward to seeing more of this....
